Hello @,
I hope this post will help you guys to resolve this issue .. I had exactly the same since few days, by running our barlist into debug mode, I saw the following error :
[ -2] OB2_CreateDirectory: mkdir() failed, errcode=31 [dir=/var/opt/omni/server/sessions/checkpoint/2014_05_30_0277]
I check on our CM (HPUX 11iv2) into the mentioned directories, and there were 32767 folders (from 2010 to now), checking at the kernel parameters, I noticed that's the limit set for HPUX for the maximum numbers of subdirectories (vx_maxlink) .. By removing some old directories, and restarting the backup, I get rid of the problem.
Bye!
