Description Andrew Noonan 2009-01-09 07:35:10 UTC
We're running httpd 2.2.10 with mod_jk 1.2.27, and sometimes after restarts, the cluster domain field, which is unspecified in our configuration, contains garbage characters for a few workers. This often causes the XML to become malformed, which for us is a particular problem as we parse the XML to provide status on our site. The workers can be edited to remove these characters and the problem doesn't seem to return, but it worries me because that data had to come from somewhere... perhaps there's another problem happening because of an under/overflow into that field.

I see the same garbage characters on the jkstatus page in the domain and redirect columns with mod_jk 1.2.27 and 1.2.28. The issue did not occur with 1.2.26. I tested with a stripped down workers.properties file and the problem went away. The issue came back once the balance_workers line had 8 or more workers listed. I am using CentOS 5.3 with Apache 2.2.3. I also am having trouble parsing the xml file returned by jkstatus because of this issue.

I got the same problem on a apache 2.2.11 with mod_jk 1.2.28. I also tested with stripped configuration and I had no problem with less then 8 workers listed. But when using 8 workers I got garbage in domain and redirect field. After inserting the route attribute (with workerhostname as value) for every 8 worker, the problem disappears.
