Web UI errors (too many open files) while runing a balance

[phillxnet (Philip Guyton)]

@TexasDex Welcome to the Rockstor community and thanks for the additional report.

Yes we still see this occasionally, you might like to take a look at the discussion in the earlier sighted open issue for this:

https://github.com/rockstor/rockstor-core/issues/1656

From that I suspected (in that thread) that it was AFP related. Do you also have AFP enabled?
Or did you have the Web-UI open over a long period?

I don’t think the LUKS element is relevant here though.

You might also like to take a look at the discussion / proposed fix by forum member @erisler in the following proposed pull request:

Possible fix for https://github.com/rockstor/rockstor-core/issues/1656 ("Too many open files" / umlimit issue)

which in turn links back to the following forum thread:

Exception while running command(['/usr/bin/hostnamectl', '--static']): [Errno 24] Too many open files

@peter appears to be on to something - it may also be related to running AFP…read on… I ran the following in ssh while seeing this error in the webui to find the processes with the most open files (credit: https://stackoverflow.com/questions/21752067/counting-open-files-per-process): cd /proc; find -maxdepth 1 -type d -name '[0-9]*' -exec bash -c "ls {}/fd/ | wc -l | tr '\n' ' '" \; -printf "fds (PID = %P), command: " -exec bash -c "tr '\0' ' ' < {}/cmdline" \; -exec echo \…

Which also links in the AFP element.

I’m afraid my knowledge in these web tech areas is far surpassed by @suman, @Flyer, and I think we are awaiting @Flyer’s final comment on the above pull request. Please do take a look at these links to see where we are up to so far on this one as it would be great to finally get to the cause on this one.

Hope that helps.
