Re: [SSSD-users] sssd fails - too many open files

[Andy Airey]

Hi,

I have the same issue.

It seems to hit a limit of 1024.

This is on CentOS 6.7.
Output below:

[root@localhost ~] ls -l /proc/`pgrep sssd_be`/fd/ | wc -l
1024
[root@localhost ~] cat /etc/redhat-release
CentOS release 6.7 (Final)


There is a way of increasing this limit, but it seems strange that we hit
this limit ...

Kind Regards,

Andy

sssd fails - too many open files

[Andy Airey]

Hello,

Yes, SSSD finds that my DC goes offline a lot (don't know why yet, other
issue), hence creating lots of sockets.

This is why I seem to be hitting this bug.
Restarted SSSD and have now 36 open files, was 28 right after restart.

Thanks for the information.

Andy

Here is the fix:

It hasn't been released yet, but Lukas has some test packages here:

What files has it got open?

I pick on a 6.7 machine with SSSD (using AD, single domain) that's been
running for a couple of months and have 27 files open.

It is reproducible only in case if LDAP server(AD from different site)
is behind firewall. And the connection is not rejected but dropped.
