I am developing a Flutter application in Android Studio. When I place a breakpoint somewhere in the code it gets hit and execution stops, but after half a second the application exits with the following error:
Unhandled exception:
FileSystemException: Cannot open file, path = 'build\app.dill.track.dill.incremental.dill' (OS Error: The requested operation cannot be performed on a file with a user-mapped section open.
, errno = 1224)

If I run application without debugging it works normally. Has anyone had similar error and solved it successfully?
The breakpoint seems to work as expected. What happens here looks like a function in the app expects a value that wasn't provided after the breakpoint. Debug the app by checking if there's any function expecting a value that's blocked by the breakpoint.

I have tried two different Viber packages available through snap, viber-unofficial.viber and viber-mtd.viber. Both packages produce the exact same error about WebEngine resources not found

I have looked at the permissions of the various directories and I don't see anything obvious other than everything in the snap package is all owned by root/root and the regular user trying to actually run the viber app does not have any write permission into these directories.
I am using zmq PUSH and PULL sockets. And recently started observing SIGABRT crash, in zmq_poll() operation.
The error/exit log is "Permission denied (src/tcp_connecter.cpp:361)"

Could anyone help me here ??
Process is a part of a container running in Kubernates. And this issue started occuring suddenly. And couldn't be able to recover.
Thanks,
Meanwhile, I resolved the issue.
The zmq interface in host A was trying to connect to Host B. And above error is observed in Host A.
And this issue started occuring once after restarting HostB. And I could notice, there is an ip6table rule got added in HostB as part of its restart. This rule was doing "reject with admin prohibited" in INPUT and forward chain in HostB. (I have to search my notes for exact rule.)
As part of this, zmq client in HostA was ending up in above mentioned crash. I believe crash (SIGABRT) should not be solution for hitting such rule in peer end. Since SIGABRT exception is unable to handle in code.
Though I am using the docker facing this issue. The same things are working fine on other systems

i have just update my Mac to Mojave with a Clean installation, so I re-installed all my apps including Android Studio and Flutter, as the first time, i followed the Flutter installation guide. I got this error at re-opening an previous project, but if i create a new Flutter project I don't have problems, I tried to remake all project copying the code but I got the same errors:

Looks like this known issue https://github.com/flutter/flutter/issues/22721
that was fixed upstream and should land in Flutter master channel soon (or has already landed)
I have a simple web app (http://www.webdungeon2.org) (6 pages) running on the latest (April 2014) version of Rikulo Stream (Ubuntu 13.04), Dart 1.2 and I get the following error when browsing (i think):

The server crashes and then I restart it. This has happened 3 times in 3 days.
I also get these (which do NOT crash the site):

Any suggestions?
UPDATE - 12 April
Problem still occurs on Dart 1.3, but error code is different
Uncaught Error: SocketException: OS Error: Connection reset by peer, errno = 104, address = 0.0.0.0, port = 80

UPDATE - 28 April
The problem seems to have been resolved in Dart SDK version 1.3.3. My server has been running for 2 days without a hitch.
Serge
Did you upgrade to Dart 1.3? The problem shall be caused by Issue 17468, and it was fixed in Dart 1.3.
For the issue of HttpException...Chunked, I don't have the experience of it. You have to check Dart API, or make a simple case to reproduce the issue.
The fix for issue 17468 contained a bug. Streams belongs to the zone where they are listened to, not created. I've fixed this mistake with r35071.
While this will not fix the 1.3 binary, it should be possible to check out the 1.3 source and apply this patch.
