turn caused the crash.

Problem summary
****************************************************************
* USERS AFFECTED: Users of WebSphere Application Server Web *
* server plug-ins. *
****************************************************************
* PROBLEM DESCRIPTION: When the system was under heavy load *
* and running out of memory, a NULL *
* pointer was returned from a memory *
* allocation call. IBM HTTP Server *
* crashed when this NULL pointer was used *
* to read POST data. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Under heavy load, IBM HTTP Server crashed when processing POST
request.
Problem conclusion
To avoid the IBM HTTP Server process crash, the plug-in should
not pass the NULL pointer to the IBM HTTP Server API. When the
system runs out of memory, the request will fail, and an ERROR
message will be logged.
The fix for this APAR is currently targeted for inclusion in
fixpack 5.02.10 and 5.1.1.4. Please refer to the Recommended
