I have ported Linux MySQL HA solution provided by HP to HP-UX platform.
My kernel has the following parameters:
naxfiles 60 (Soft File Limit Per Process)
maxfiles_lim 1024 (Hard File Limit Per Process )
I see that mysqld can reach maxfiles_lim, but I don't understand where it is allowed.
open-files-limit parameter is not set in my.cnf, no ulimit command can be found in other files.
Many thanks and points in advance for clarification of this default behavior!

Re: open_files_limit for mysql
make maxuprc 200 to 300
Bump the files limits up.
This needs to be handled in the kernel.
kmtune ouput to check it.

Re: open_files_limit for mysql
I tried to find out, where mysqld process is allowed to reach maxfiles_lim, if soft limit is small. Is it necessary to allow it explicitly?

SolutionMy guess is that if you search MySQL source code, you will find instances where soft limit is increased using setrlimit(2).
