Too many open files during a patching operation

Support
#1

I was applying patches to a system yesterday and ran into a problem.

The yum transaction (initiated from Katello as part of a host_collection
update operation) failed with a "too many open files" type error.

Everything after that was just more of the same (Too many open files).

Do I need to bump up the number of open files for goferd?

Hi Tony,

Based on the output below this error appears to be coming from yum. Since yum transactions typically require root access it would seem that you have limited the number of open files for the root user.

Have you intentionally lowered the number of open files on your system? I would check the output of "ulimit -n" on the system that failed.

Regards,
