Summary: If the tomcat server cannot be resolved, apachectl
configtest passes, but apachectl graceful fails
Product: Tomcat Connectors
Version: 1.2.28
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: mod_jk
AssignedTo: dev@tomcat.apache.org
ReportedBy: mchy...@yahoo.com
We had a production issue where we added some servers, and configured them in
workers.properties. However, some web servers didnt have the app servers in
the /etc/hosts file. So the host names were not resolvable. We did an
apachectl configtest
and it passed.
Then we did an
apachectl graceful
And apache died. We figured out the problem, but I think mod_jk should either:
1. Check for host resolution on a configtest
-and/or-
2. Not fail to start if a host is not resolvable. Maybe throw an error, but
dont kill apache.
Here is the error we saw in mod_jk.log (note, the server name not resolvable is
"pats")
