Thanks for your reply.
Actually, I meant forceload: sys/semsys
I have a third party middleware package which is loaded at boot time.
It uses shared memory and semaphores. When the server is rebooted, the
the middleware performance is terrible. If I restart the daemons manually,
everything works fine. So I suspect that when at boot time ,
the middleware starts, there are some race conditions related to the fact that
shared memory and semaphore support are loaded at first reference. Can this
make sense? Would forceloading IPC help?
