We have an application here that relies heavily on SYSV semaphores and
message queues for IPC. The problem is that under heavy system loads
(lots of swapping), either a message queue loses a message or a semaphore
doesn't get decremented when it should. Does anyone know of any
bugs in the IPC code relating to this, or perhaps related to being
knocked off a pending semaphore call by a signal? We are running
Sys V Rel 2 Version 2, if that's any help. Please reply
directly to me at ...!ihnp4!cbm!hutch!barber, and I will summarize
to the net. Thanks in advance.
