Subject DEBUG com.ecyrd.jspwiki.util.WatchDog - dumping stacktrace for too long running thread : Thread[http-80-4,5,main]
Date Fri, 27 Jan 2012 00:13:20 GMT
We have 4-5 JSPWikis running on virtual hosts under tomcat.
ONE of these virtual host continues to have issues.

We recently updated to JSPWiki v2.8.4 form 2.6.? and we still struggle with
this one site.

With debug logging enabled, we see this repeat over and over again:
2012-01-26 19:00:08,876 [WatchDog for 'Wikiwilleke'] DEBUG

org.apache.commons.jrcs.diff.Diff.diff(Diff.java:144)


When we edit a page and save the page, the page will hang with all button
disabled.

We are using container authentication but have almost no issues with any of
the other sites.

Any ideas?

Thanks
