Re: [xwiki-users] crash on tomcat 7.0.47 with xwiki 5.4.2

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... ------------------------------ *De :* Jeremie BOUSQUET &lt;jeremie.bousquet(a)gmail.com&gt; *À :* Pascal BASTIEN &lt;pbasnews-xwiki(a)yahoo.fr&gt;fr>; XWiki Users < users(a)xwiki.org&gt; *Envoyé le :* Lundi 17 mars 2014 16h49 *Objet :* Re: [xwiki-users] crash on tomcat 7.0.47 with xwiki 5.4.2 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. BR, Jeremie
