Nodejs to Couchbase Server timed out - node.js

My app is actually running fine when I started it and keep an eye on it for few hours.
BUT later time(I'm not sure what exact time of inactivity), It does show "Server timed out" (I crop some logs below)
[ERROR] (server - L:463) <node.mycouchbase.server:11210> (SRV=0x2111c60,IX=4) Server timed out. Some commands have failed
[INFO] (confmon - L:166) Not applying configuration received via CCCP. No changes detected. A.rev=152466, B.rev=152466

[INFO] (cccp - L:110) Re-Issuing CCCP Command on server struct 0x2185e30
All just working fine again when I restart my Node.js app (Expressjs app).
This problem seem regularly happening
Please give me some suggestion what could be actually problems behind.
Thanks

arangodb starter mode does not start

I have d/l'd arangodb3-linux-3.9.2 from GIT on Centos 7. I created a database dir and ran the README instructions for a standalone start. The first time it runs, I get 100 failures, the key INFO log lines seem to be
... [INFO] server started component=arangodb pid=49827 type=single
... [INFO] Wait on 49827 returned component=arangodb exit-status=1 trap-cause=-1
It creates the log file, setup.json and a single8529 dir in the database dir I sped'd. Is it just taking too long to start? The whole 100 fails take about 1 or 2 seconds.
If I try to run it again with the same README instructions, the next time I get this error:
... [FATAL] Failed to run service error="open /.../single8529/data/ENGINE: no such file"
I have also tried with --starter.host 127.0.0.1 -- to simplify
Also I and can confirm that port 8529 is open
I couldn't get arangodb 'starter' according to their README to work, but this does start the server:
arangod --database.directory MYDIR --rocksdb.max-background-jobs 4

Can't upload iOS dSYM file to Flurry

I used to upload iOS dSYM files to Flurry by referring to the following site, but suddenly stopped working.
https://github.com/flurry/upload-clients
1.Download symbols from AppStoreConnect
2.Run the script using the -p argument. eg.
./upload-symbols.py -c flurry.config -p ~/Downloads/dSYMs.zip
Then this was displayed on console.

Error: Internal Error: 1005
What's not working?
The problem with uploading dsyms has now been fixed.
Still facing the same issue with Flurry SDK version 11.4.0. The issue doesn't always occur, but it sure repeats.
What I think is that the problem is with the flurry server as its successful response rate is nearly 86 percent. When it fails the server might be failing to respond during the build(script execution). Tried building on multiple devices and networks. The issue still persists.
If you find a solution that works and the reason why it does, It would be of great help.

Anchore Engine - Jenkins CI plugin

We are trying to scan our docker images using Anchore Engine Jenkins plugin.
Currently we create our application docker images, push it in our own private local registry and then deploy it in our test environments.
Now, we want to setup docker image scanning in our CI/CD process to check for any vulnerabilities.
We have installed Anchore Engine using the recommended Docker-Compose yaml method given in the Documentation link:
https://anchore.freshdesk.com/support/solutions/articles/36000020729-install-on-docker-swarm
Post installation, we installed the
Anchore Container Image Scanner Plugin in Jenkins.
We configured the plugin as mentioned in the document link:
https://wiki.jenkins.io/display/JENKINS/Anchore+Container+Image+Scanner+Plugin
However, the scanning fails. Error Message as follows:
2018-10-11T07:01:44.647 INFO AnchoreWorker Analysis request accepted, received image digest sha256:7d6fb7e5e7a74a4309cc436f6d11c29a96cbf27a4a8cb45a50cb0a326dc32fe8

Unfortunately we are not able to find much resource online to try and resolve the above mentioned issue.
Anyone who might have worked on Anchore-Engine, please may I request to have a look and help us resolve this issue.
Also, any suggestions or alternatives to anchore-engine or detailed steps in case we might have missed anything would be really appreciated.

When images are added to anchore-engine, they are queued for analysis which moves them through a simple state machine that starts with ‘not_analyzed’, goes to ‘analyzing’ and finally ends in either ‘analyzed’ or ‘analysis_failed’. Only when an image has reached ‘analyzed’ will a policy evaluation be possible.
The anchore Jenkins plugin will add an image, then poll the engine for image status/evaluation for the configured number of tries (default 300). Once the image goes to ‘analyzed’ (where policy evaluation is possible), the plugin will then receive a policy evaluation result from the engine.
The plugin will fail the build (by default) if the max retries has been performed and the image has not reached ‘analyzed’, if the image does reach ‘analyzed’ but the policy evaluation is producing a ‘fail’ result (meaning the image didn’t pass your configured policy checks). Note that all build failure behavior can be controlled in the plugin (I.e. there are options to allow the plugin to succeed even if the analysis or image eval fails).
You’ll need to look at the end of the output from your build run (instead of just the beginning from your post), and combined with the information above, it should be clear which scenario is causing the plugin to fail the build.
We have resolved the issue.
Root Cause:
We were not able to establish a successful https connection to URL : https://ancho.re from within the anchore-engine docker container.
As a result the service:policy_engine was not able to start.
https://ancho.re is required to download policy feeds and sync-up periodically. Without these policy anchore-engine won't be able to analyse the docker images.
Solution:
1) We passed a HTTPS_PROXY URL as an environment variable in the docker-compose.yaml of anchore-engine.
We used this proxy URL to bypass restrictions in our environment and establish a connection with https://ancho.re url.
2) Restarted the docker containers.
Finally we got all services up and running including Anchore policy-engine.
FYI:
It takes a while to download all the required Feeds depending on your internet speed.
Lastly, Thanks to the Anchore community for quick responses and support over slack.
Hope this helps.
Warm Regards,
Rohan Shetty

canvasengine Tiled_server Error: ENOENT, open './map.json'

This is my problem:
I try start Canvasengine example server and I get this error.

Error: ENOENT, open './map.json'
at Error (native)
map.json is there, but nodejs can't find that file.
Server have Debian 7, nodejs, Socket.io and CanvasEngine 1.3.0
Looking at the code, you should either copy map.json to your working directory (which seems to be /, so I wouldn't necessarily recommend that) or start the server from its respective directory:
$ cd /var/www/canvas/canvasengine/examples/tiled_server/server/
$ node server
(although this may require setting $NODE_PATH)

I have seen this reported in a number of places but no solution. Is this error because we are behind a corporate firewall, or is this due to something else? Please advise.
I had proxy set as environment variables, but it appears they are not being picked up. Adding them in sbt directly worked for me.
Edit $SPARK_HOME/sbt/sbt
For example,
EXTRA_ARGS="-Dhttp.proxySet=true -Dhttp.proxyHost=myproxy.mycompany.com -Dhttp.proxyPort=80 -Dhttps.proxySet=true -Dhttps.proxyHost=myproxy.mycompany.com -Dhttps.proxyPort=80 -Dftp.proxySet=true -Dftp.proxyHost=myproxy.mycompany.com -Dftp.proxyPort=80 -Dhttp.nonProxyHosts=mydomain -Dhttps.nonProxyHosts=mydomain -Dftp.nonProxyHosts=mydomain"
