Error description
OutOfMemoryError in the Session Initiation Protocol (SIP) container.
Local fix
N/A
Problem summary
**************************************************************** * USERS AFFECTED: Session Initiation Protocol (SIP) users of * * IBM WebSphere Application Server Feature * * Pack for Communications Enabled * * Applications (CEA) * **************************************************************** * PROBLEM DESCRIPTION: Application server runs out of memory * * because outbound message queue * * overflows. * **************************************************************** * RECOMMENDATION: * **************************************************************** The problem occurs when the server is trying to send a large number of SIP messages at a high rate, and the underlying TCP connection cannot keep up with the load. Over time, this may lead to memory exhaustion, since there is no limit on the queue size.
Problem conclusion
The problem is fixed in the SIP container code, by placing a limit on the number of messages queued for delivery, per connection. If the queue overflows, the connection is closed down, rather than exhausting the entire server memory. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.13 for the Feature Pack for Communications Enabled Applications.
