Error in level 0 archive
A user on Informix Dynamic Server 9.21 (IDS 2000) could no longer run a level 0 ontape archive; the online log showed "shmget: [ENOMEM] ... out of shared memory, check system max shared memory segment size", "out of virtual shared memory", and an assert failure in init_arcbu()/SCBMALLOC() (rsarcutl.c line 126) with a stack trace written to /tmp. The only reply noted the poster hadn't said which platform he was on and suggested the shmget message was literally the cause, i.e. check/raise the OS kernel shared-memory parameters. No confirmed resolution is recorded in the thread.

You haven't stated your platform.
Could it just be that this bit:
> 10:38:37 shmget: [ENOMEM][12]: key 5257481a: out of shared memory,> check system max shared memory segment size
is the whole truth, and you need to check your kernel parameters?
