OAM 10g Identity Server Randomly Consumes Memory Then Crashes In Environment Using IDXML (Doc ID 1486426.1)

Last updated on MARCH 12, 2019

Applies to:

COREid Identity - Version and later
Information in this document applies to any platform.


Oracle Access Manager (OAM) 10g Identity Server (OIS) crashes randomly. For example it crashes once a day, 3 times a day or one time in 5 days.
Immediately prior to the process crash / core it is seen that the ois_server process is consuming a large and continuously increasing amount of memory.

There is one or more applications which issue IDXML requests to OIS.

If there is a high availability configuration with multiple WebPass and OIS nodes, the crash occurs on whichever of the OIS servers is "active" i.e. used by the application.

When the problem occurs messages like the following are seen in the Windows application event log:


Restart of the OIS service restores the service while the application switches over to using the other OIS node. But the problem occurs within a short time on the other node then.

It is unknown what triggers the problem.
