[comp.sys.apollo] Problems with inter process commnication

XBR4DB26@DDATHD21.BITNET (OLAF THUN) (11/05/90)

We are running a selfmade programmsystem with up to 8 indepented
processes. They communicating with ipcs to sysnchronize them.
But very often we have problems with the ipcs. The errormessage is:

socket empty  by the call ipc_rcv()

Before we try to receive the ipc we wait for it with the function
ipc_wait(). If this function returns with the status OK we try to get
the datagram with ipc_rcv(). Then we often get the errormessage socket
empty.

Can anybody help us?

We have DN3000 and DN3500 maschines with AEGIS 9.7.
