Tracing the problem showed that MPROUTE was not releasing all storage after the SMSG command processing was complete. LOCAL FIX: PROBLEM SUMMARY: **************************************************************** * USERS AFFECTED: ALL USERS OF MPROUTE * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** When SMSG MPROUTE is executed repeatedly, an out of storage condition occurs. This can be recreated by running an exec that loops forever issuing SMSG MPROUTE commands. PROBLEM CONCLUSION: For every SMSG issued by MPRoute, a call to BeginTcpip and EndTcpip is made. The storage allocated during InitNoteQueue is not released in EndTcpip. If enough SMSGs are issued, storage is exhausted. A new routine DisposeNoteQueue was added to CMERUPT and called by EndTcpip. DisposeNoteQueue disposes of the memory obtained for NoteFreePool, NotePullQueue, and NotePushQueue.
