Heap shows accumulation of DBLockProviderImpl objects
System administrators have noted a growth in heap size over time. Inspection of heap dumps show a buildup of objects of class DBLockProviderImpl$LockInformation.
Steps to Reproduce
This is occurring in an application that is exposed through a web portal - where there is no way to control or prevent users from abandoning sessions without logging off cleanly.
A defect in Pegasystems’ code allows accumulation of objects in the LockCache (objects of class DBLockProviderImpl$LockInformation).
