Subject RE: 2.0.28 and mod_jk
Date Fri, 09 Nov 2001 17:33:09 GMT
Hi,
	Thanks for the feedback.. I have some progress here : With
worker-mpm (everything else remain the same), I don't see any core-dumps..
Infact, I get the foll. error in my error_log :

"[Fri Nov 09 00:32:40 2001] [info] [client 15.13.190.67] Module bug?
Request fil
ename path <NULL> is missing or not absolute for uri /examples"

It sure is a module bug.. I'll investigate further on Bill's suggestion, and
will also check out the jakarta-tomcat-connectors cvs tree..

Thx very much,
-Madhu
