Each invocation accesses shared memory for a performing task. This all works with Cygwin1.3 Now We are using Cygwin 1.7-58 with windows 2008 after this The number of attached processes keeps on increments and due to which system resource gets full. None of the process get detached from shared memory With Cygwin 1.7-58 When I run through my application, it will give successful response for 3 messages out 5 messages and my client application hangs. My Error log file has recorded the following statements: CU-E-3404(3196):Unable to Send Communication Packet (CUP) on Queue. msgsnd-E-3011(3196):EAGAIN No more processes.. Our application uses IPC functionalities for sending and receiving messages from other application. I have made the following configuration for message queue, shared memory and semaphore MSGINFO: MSGMAX: 4096 MSGMNI: 50 MSGTQL: 400 MSGMAP: 402 MSGMNB: 16384 SEMINFO: SEMMNI: 200 SEMMNS: 128 SEMMNU: 150 SHMINFO: SHMMNI: 100 SHMMAX: 2000000 So please... can any one suggest where m going wrong and please give me the possible solutions for it. Your help is really appreciated. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
