I just yum updated a CentOS box to 5.2 (kernel 2.6.18-92.1.1, i386), and now openserctl start no longer works. When I try it, I get this in the messages file:

Jun 27 08:44:49 proxy1 openser: CRITICAL:core:shm_getmem: could not attach shared memory segment: Invalid argument

Jun 27 08:44:49 proxy1 openser: CRITICAL:core:init_shm_mallocs: could not initialize shared memory pool, exiting...

I can start openser with /usr/local/sbin/openser, and it starts fine. The openserctlrc file is the same as it is on each server I have, it works everywhere else. I try turning up logging, turning on debug, and I get nothing but those two lines in the log.

Any ideas?
