JK2 release & Expat

[Gr...@pfizer.com]

Hi All,

I've been trying to test jk2 as we have a little buglet with 2.0.2 (it
appears apache children get confused, and hang whilst/after dealing with jk2
served content, they then hand around and clog up the process list, and
eventually we hit MaxClients).

Due to many reasons we run an older version of Apache (1.3.26).  This has
been complied with --disable-rule=EXPAT due to mod perl.

However when I start up an apache with the new jk2.so I get:

Cannot load /var/tmp/mod_jk2_new.so into server: ld.so.1:
/WWW/app/apache/1.3.26c/bin/httpd: fatal: relocation error: file
/var/tmp/mod_jk2_new.so: symbol XML_GetErrorCode: referenced symbol not
found

Which appears to be an Expat error.

Is this a new issue with apr or apr-utils?

Any clues?  Or is Expat now required within apache.  If so this could cause
a problem with running jk2 in a mod_perl moduled apache.

Thanks for all your efforts.

Greg

a "ldd /var/tmp/mod_jk2_new.so" would be nice to have.

For the jk2 in CVS APR is mandatory so you should rebuild apr with expat
