xwiki.org has restarted. It should be fine now. -Vincent

Hello, It may be something else (see error about AsyncHttpClient-Callback), but basically it seems you JVM is missing memory. 800m may be a bit too small. I know it's the recommendation for large installs, but in my case at least I had to put more than that (about 1724m, but there's no "generic" number of course). Is your wiki very "big" ? (in terms of number of pages for example) Also it seems a bit weird that "PermSize" is larger than "MaxPermSize" in you OPTS.

You need to increase permanent space (parameter -XX:MaxPermSize), which is used for static objects, and which is never deallocated, e.g. -XX:MaxPermSize=256m

Hello,

With xwiki 5.4.1 I hadn't crash of xwiki but with the last version 5.4.2 I have 2 crash per day... Log indicate : "java.lang.OutOfMemoryError: PermGen space"

Here my catalina.sh

JAVA_OPTS="-server -Xms800m -Xmx800m -XX:PermSize=64M -XX:MaxPermSize=196m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100 -Dhttp.proxyHost=beast.dom.cpii.i2 -Dhttp.proxyPort=8080"

and the log

_______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users

With PermSize equal to 256m, I had no outofmemory permgen anymore, but I'm not on same system, and not on same xwiki version, so it doesn't mean much ... But if you had no issue with 5.4.1, there may be some something either "memory-demanding" in new wiki version, or some leak or whatever ... 2014-03-17 17:18 GMT+01:00 Pascal BASTIEN <[email protected]>:

Oups about permsize! :-/

Thxs I try that then: JAVA_OPTS="-server -Xms1724m -Xmx1724m -XX:PermSize=256M -XX:MaxPermSize=512m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100 -Dhttp.proxyHost=beast.dom.cpii.i2 -Dhttp.proxyPort=8080"

For instant, we are me and ... my boss on xwiki and there aren't a lot of page. But in 2 weeks we will be 1000 or more...
