I'm just ringing in, although I don't have a vote. I was working with
Rainer on an issue with 1.2.21 on some Red Hat machines. I started with
mod_jk because those were the only error messages I was getting. It
turns out that those messages were not related to my ultimate problem.
Thanks again to Rainer for helping me track that down and sort it out.
My ultimate problem was that apache was returning bad data in some
requests, but logging 200 error code and the proper file sizes in the
access_log. The files themselves were of variable size and often
contained other "junk" that was obviously from apache memory space
(chunks of log entries and other things).
The theories I went though included targeting sendfile, mmap, and
mod_cache (mod_cache_mem) . I disabled all of these and still was
experiencing the problem.
Eventually I stopped it from happening by switching from mod_jk to
mod_proxy_ajp. I still have the other things enabled.
Since I'm not a developer I can't say exactly where that problem might
be. It does seem as though there is some problem there. I couldn't
reproduce it with ab... apache thinks everything is normal. It didn't
show up until I put the servers in production, and then it was only a
small percentage of overall requests. If I hadn't seen the b0rked
images and files through my browser I would not have known the problem
existed.
I'd be happy to help troubleshoot this if anyone wants to investigate
further.
Thanks;
Eric

Well it shouldn't stop the release since it may be related to iSeries

I should check about compile flags (we don't use configure on iSeries)
and may be I miss something but it seems related to logging area ;(

Henri,
since this alredy happened in 1.2.20 and it runs well on most platforms,
think it should not stop the release. But I'm still very interested in
fixing his.
In your last problem report, I think I saw a stack trace from which we
could see the method, were the crash was happening. Maybe we can then
build a debug version, to find out, which things didn't get initialized
properly.
Regards,
Rainer
