Semaphores on scounix

We are having an ongoing problem with our ATS machine locking up. Each time this occurs, it appears that the semaphores appear as shown below. I would like to either eliminate or charge this area as being associated with the problem. All responses are appreciated. $ipcs IPC status from /dev/kmem as of Thu May 15 15:35:18 1997 T ID KEY MODE OWNER GROUP Message Queues: Shared Memory: m 0 0x52564801 --rw-rw---- informix informix m 401 0x0000faee --rw-rw-rw- informix root m 2 0x0000faff --rw-rw-rw- informix root m 32003 0x0000fadd --rw-rw-rw- informix informix Semaphores: s 0 0x52564801 --ra-ra---- informix informix s 1 0x52564802 --ra-ra---- informix informix s 2 0x52564803 --ra-ra---- informix informix s 3 0x52564804 --ra-ra---- informix informix s 4 0x52564805 --ra-ra---- informix informix s 5 0x52564806 --ra-ra---- informix informix s 6 0x52564807 --ra-ra---- informix informix s 7 0x52564808 --ra-ra---- informix informix s 8 0x52564809 --ra-ra---- informix informix s 9 0x5256480a --ra-ra---- informix informix s 10 0x5256480b --ra-ra---- informix informix s 11 0x5256480c --ra-ra---- informix informix s 12 0x5256480d --ra-ra---- informix informix s 13 0x5256480e --ra-ra---- informix informix s 14 0x5256480f --ra-ra---- informix informix s 15 0x52564810 --ra-ra---- informix informix s 13 0x00000000 --ra------- lookatdb informix | This appears s 14 0x00000000 --ra------- lookatdb informix | very s 15 0x00000000 --ra------- lookatdb informix | suspicious Randall D.
