Workaround for JK Bug
All,
I have recently encountered a bug in the interaction between mod_jk and Tomcat. In brief, Tomcat does not get the POST data from mod_jk following failover from one Tomacat node to another.
It appears that this bug is known, and has been posted to this list before:
http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg110113.html
http://www.junlu.com/msg/15381.html
I wonder, have any others on the list experienced this?
Has anyone found a workaround?
If there is no workaround using Apache, mod_jk and Tomcat, how are people achieving load balancing and failover?
Also, here is a link to the bug in Apache's Bugzilla:
http://issues.apache.org/bugzilla/show_bug.cgi?id=24882
Thanks in advance, everyone!
Chris

mod_jk2 is due to be tagged for a release in the next week or so. mod_jk
is due to be tagged the week after mod_jk2 is released. If you are
affected by the POST bug in mod_jk, then I would consider using CVS after
testing it yourself, otherwise I would just wait.

i was wondering what the state of the checked in code is for mod_jk. the
last tag on jk was 1.2.5 after which (i assume) there have been several
checkins.
would you recommend pushing out a cvs built mod_jk to production (probably
unsafe, right) or should we wait for the next tagged, jakarta-blessed,
deemed stable mod_jk?
(i guess i answered my question... any thoughts, gut-feelings,
recommendations anyone?)

It's in all releases besides current CVS. The bug isn't that easy to
trigger which is why it's gone un-fixed for some time.

Is this issue only in the binary release or all releases?
I have jk 1.2.4 with apache 1.3.29 compiled from source on solaris but
have not observed this problem.

It's should be fixed in CVS. Try pulling the latest code and see if it
fixes it for you and post your results in the bug, the developers would
love to hear about it.

It's should be fixed in CVS. Try pulling the latest code and see if it
fixes it for you and post your results in the bug, the developers would
