I've been getting these errors while/after trying to upgrade to XenForo 2.2.8 Patch 1:

Code:

How do I fix this so that the Xenforo update can complete? Or what's the best way to resolve this?

Turned out to be exactly what is suggested: number of open files set too low.

RLIMIT_OFILE

Previously set to about 1024. Reset to 4096. Still too many open files.

Reset to 8192. No errors.
