Problem summary
**************************************************************** * USERS AFFECTED: Session Initiation Protocol (SIP) users * * of IBM WebSphere Application Feature Pack * * for Communications Enabled Applications * * 1.0.0.1 * **************************************************************** * PROBLEM DESCRIPTION: The SIP container opens multiple * * connections to the same destination, * * and keeps them open for the entire * * process lifetime. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the application sends multiple messages to the same destination over stream transport (either TCP or TLS) at the same time, the container creates a separate connection for each message. The connections remain open for the entire process lifetime. Under load, this problem may lead to resource exhaustion.
Problem conclusion
The problem is fixed in the SIP (Session Initiation Protocol) container. With this fix, the container never creates more than one outbound connection to the same target. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.1 for the Feature Pack for Communications Enabled Applications.
