JRoller down until after soccer practice.
After months of relatively trouble free operation, JRoller is straining against the load of 3980 users and heavy traffic. I adjusted some of JRoller's mod_jk2 settings today and restarted the server. It failed to start, so I reversed my settings change and tried again - still no luck. Unfortunately, I'm not going to be able to touch the system until tonight, after I get off work, take the kids to soccer practice, and to the end-of-season dinner. Sorry JRollers, I'm a soccer dad first and a JRoller admin second. Matt Schmidt may be able to do something after he gets out of class this afternoon.
Update - 11:30PM EST - JRoller is back up. JRoller's JIRA instance should be up shortly.
