Hi,
When I arrived into the office this morning our Nagios server was displaying a lot of
alarms.
The "sssd_pam" process was consuming 100% CPU, and I was unable to log on to the
box as anything
else than root.
2310 root 20 0 219m 44m 2176 R 99.6 0.3 2883:27 sssd_pam
In the var/log/sssd/sssd_pam.log file, the following error message was repeated:
[sssd[pam]] [accept_fd_handler] (0x0020): Accept failed [Too many open files]
This being our Nagios server the maximum amount of concurrent open files has been
increased from
the default 1024 to 4096 for all users.
This is RHEL 6.3 with sssd-1.8.0-32.
What can I do to prevent this from happening in the future?
Regards,
Siggi
