Where could be ulimit -v global setting stored?

I can increase virtual memory by ulimit -v INTEGER, but this command affects only my current session.
In these files I have not defined ulimit -v
me#server:/home/me : cat /etc/profile | grep ulimit
# ulimit package instead to set up ulimits and your PATH.
# ulimit -Sc 0 # don't create core files
# ulimit -Sd $(ulimit -Hd)
# ulimit -Ss $(ulimit -Hs)
# ulimit -Sm $(ulimit -Hm)
me#server:/home/me : cat /etc/security/limits.conf | grep ulimit
me#server:/home/me :
Where could be virtual memory value 9695920 defined or where is it from?
Thanks for your help.
s.
ulimit -v is in /etc/initscript calculated from MemTotal and SwapTotal
me#server:/proc : cat ./meminfo
MemTotal: 7925532 kB
SwapTotal: 4194300 kB

I have a Rails 6 application with Webpacker on a virtual host using Plesk. Node.js packages have been successfully installed with yarn.
When calling the website, Phusion Passenger fails with:
And the Stdout/stderr output of the failing subprocess just prints the first 65412 characters of my public/packs/js/application-ad2c73bce874600d5502.js file, without any more error details... What does that mean, and how can I get it running?

The JS file was minified, thus containing a single line only. I downloaded the file, run some code formating, and uploaded the resulting content with ~25000 lines by replacing the original minified content. Then I could see the line responsible for the error, and also error message and backtrace.
I am using the Linux 12 SP2 . It always failed to create the thread when the thread is more than 420 .
Error log:
Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread (424 threads running, rlimit: STACK 8192k, CORE 0k, NPROC 30654, NOFILE 16394, AS infinity, DATA infinity, CPU infinity, FSIZE infinity, MEMLOCK 64k , Memory: 4k page, physical 528062120k(345461208k free), swap 2097148k(2097148k free) )
From the log, you can see the server capacity is good enough for more thread creation. Actually there is quite a few thread is running under OS . Do you have any idea about this issue ?

I'm running Linux OS (Ubuntu) on virtual box. When I am running the command
ulimit -Sv 50
It's not setting the soft limit for virtual memory size in that bash session. The error I'm getting is:
fatal error: out of heap memory
I was running above command with sudo access. The output of ulimit -a is as follow:
-t: cpu time (seconds) unlimited
-f: file size (blocks) unlimited
-d: data seg size (kbytes) unlimited
-s: stack size (kbytes) 8192
-c: core file size (blocks) 0

I ran a binary with AFL using memory size (-m) = 50 MB. So, I need to run this binary (without AFL) with the same memory size. Any insights will be helpful.
Looks like you are setting limit to 50 kilobytes and not 50 megabytes (see units in help ulimit).
I am trying to get guitarix and jack running on the Raspberry Pi 2 (+ Cirrus audio card) with raspbian.
When starting jack via qjackctl, I get the errors
Cannot lock down 82278944 byte memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/10)(1: Operation not permitted)
It seems changes to /etc/security/limits.conf do not apply but to /etc/security/limits.d/audio.conf do.
I tried setting the memory lock size for the user and group:
#audio - rtprio 90 # maximum realtime priority
#audio - memlock unlimited # maximum locked-in-memory address space (KB)
#audio - nice -10
pi - rtprio 90
pi - memlock unlimited
pi - nice -10
From ssh I get a satisfactory result:

But from the desktop terminal I access via vnc I get
pi#raspberrypi ~ $ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0

How can the same user have different settings and how do I get rt and memory allocation running on the desktop?
It seems to have been a problem with the PAM configuration as stated here.
Uncommenting the line in /etc/pam.d/su did the trick.
# session required pam_limits.so
I'm using 32bit Amazon Linux (Centos?). Per the blog http://gnufreakz.wordpress.com/2009/08/12/increase-ulimit-in-centos/ I tried changing some parameters.
I added the below line to /etc/sysctl.conf
fs.file-max = 65536
and ran sysctl -p
I added the below line to /etc/security/limits.conf
* hard nofile 65536
No luck! After a restart, ulimit -a still gives me:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 26597
max locked memory (kbytes, -l) 64

max user processes (-u) 1024
virtual memory (kbytes, -v) unlimited

Try adding
ulimit -n 65536
to your /etc/profile or to /home/[username]/.bash_profile
