Informix 9.40 crash after stress test.

Hi , I had install informix 9.40 UC2 on AIX 5.2. did anybody has idea how to check informix server is using tcp connection and not shared memory connection.How to check memory leak in informix server ? Here is some portion of online.log file . =============================================================== 16:28:31 shmat: [EMFILE][24]: out of shared memory segments, check systemSHMSEG 16:28:31 shmdt: errno = 22 16:28:31 out of virtual shared memory 16:28:31 shmat: [EMFILE][24]: out of shared memory segments, check systemSHMSEG 16:28:31 shmdt: errno = 22 16:28:31 out of virtual shared memory 16:28:31 Assert Failed: No Exception Handler 16:28:31 IBM Informix Dynamic Server Version 9.40.UC2 16:28:31 Who: Session(16, informix@adolphus, 5002, 40215d00) Thread(40, sqlexec, 401e5e68, 1) File: mtex.c Line: 431 16:28:31 Results: Exception Caught.
