ERROR DESCRIPTION:
Dynacache has two spots leading to unrestricted growth in the internal push-pull table.

LOCAL FIX:
none

PROBLEM SUMMARY

USERS AFFECTED:
WebSphere® Application Server users who use the distributed replication service PUSH-PULL mode.

PROBLEM DESCRIPTION:
The Dynamic Cache Push-Pull table is growing too big because the table is not being cleaned up in two cases.

RECOMMENDATION:
None

The Dynamic Cache Push-Pull table is not being cleaned up in the following cases when running Push-Pull mode:

1. After fetching the cache entry from the peer server, the cache id is not removed from the Push-Pull table.
2. When performing the dependency id invalidation, the cache ids associated with dependency id in the memory are not removed from the Push-Pull table.

PROBLEM CONCLUSION:
This fixes the memory leak in Dynamic cache caused by DRS Push-Pull table not being cleaned up.

The fix for this APAR is currently targeted for inclusion in 5.0.2.14, 5.1.1.8 and 6.0.2.5.
