This is an internal corporate wiki and it only blows up when I try to go to "dynamic pages" as I mentioned above.

The thread dump alone is too big to really put on pastebin but nonetheless: Xwiki.log: http://terracotta.pastebin.com/m3733cc04 Catalina.out: http://terracotta.pastebin.com/m8eaf221 I think "TP-Processor12" looks pretty suspect here. > > At the very least this could be a denial of service attack because I'm > > sure it > > must be because of some entry someone made. > Unlikely. Well, the version of Xwiki hadn't changed, nor tomcat, nor java. One day it's been running for months without issue and the next it is eating CPU every time I try to look at What's New or Blogs. What should I be looking at besides users posting? I've opened XE-351 to track the issue.
