![]() APAR status Closed as program error. Error description When more than 120 concurrent user logged in to the applicatio and if the application runs for longer time (during stress test or any other test) the out of memory exception is thrown.

Propagation issue. Internal defects (244241 and 251435) In a multi node environment, it may not be noticed until an application fails over to this node and may get org.omg.CORBA.NO_IMPLEMENT exception. Looking back on the same thread, the org.omg.CORBA.NO_PERMISSION may be found.

This problem occurs under stress, for example when more than 120 concurrent users are logged in to the application and the application runs for a long time.Problem conclusion Various problems with attribute propagation can cause session credential cache misses which causes multiple credentials and and cache entries to be created for the same identity, eventually leading to an OutOfMemory exception. Theis fix backports several fixes from Version 6.1 to V5.1. These defects correct the propagation problems. The fix for this APAR is currently targeted for inclusion in cumulative fix 5.1.1.17.
