Re: OMSA 8.3.0 not starting or segfaulting

Hi Stefan,

Thanks for providing this. Based on this strace output, I think the number semaphores has reached the maximum count on your server. If possible, Reboot the server and see issue resolves.

Also, send us the output of "ipcs -s" command.

Regards
Chandra
