ipcs -M shows:
shminfo:
shmmax: 134217728 (max shared memory segment size)
shmmin: 1 (min shared memory segment size)
shmmni: 192 (max number of shared memory identifiers)
shmseg: 128 (max shared memory segments per process)
shmall: 8192 (max amount of shared memory in pages)
So yes, it had definitely reached its max.
So I used ipcrm to remove all of the shared memory segments, and the
problem seems to have cleared up for now. A few rounds of simulating
failed logins to sshit shows that it does allocate shared memory
segments, and every time it adds an IP address it seems to allocate a
new shared memory segment instead of finding the old one.
But from here it looks like an issue to take up with the developer,
since it seems to be a bug. Thanks Bill for your help!
