Hi,
We are facing an issue related to Apache 2.0.63 (32-bit) on AIX 5.3 (64-bit):
child process crashes when serving request. We use latest IBM XL C compiler for
AIX (9.0.0.2)
Steps performed:
1) build zlib and openssl 0.9.8g static libraries (32-bit)
2) configure and build apache 2.0.63
configure flags:
CC="xlc_r"; export CC

The HTTP request which causes Apache child crash is for /iCareConsole and should
be handled by weblogic-handler (i.e. it is not excluded by directive
WLExcludePathOrMimeType).
If I disable second WLExcludePathOrMimeType parameter (in location /APUS ),
problem seems to be resolved: child is no longer crashed and requests are
processed normally. However, Weblogic documentation specifies that this
parameter can be defined locally at the Location tag level as well as globally

The crash is inside a third-party module, presumably WebLogic, please report it
to the vendor.
