[xwiki-devs] myxwiki.org status

Hi, myxwiki.org seem to crash quite a lot recently and we have also detected that it's using a lot of CPU (compared to many other services that XWiki SAS is running). I've taken a memory dump of myxwiki.org to give it a look. I see in the memory analysis 400Mb in the velocimacro structures. This could be normal as there are some caches of macros for each wiki (and there are a lot of wikis), however this is a lot and should be looked at. I've put the page http://www.myxwiki.org/xwiki/bin/view/Admin/CheckVelocityManager to check if we see any macros being cached that should not be (like the bug we had on USH). In any case, in multiwiki we have an issue with cache of velocity macros which can grow pretty big without any cleaning up when the wiki is not accessed. I've also closed registration on the main wiki (there seem to be spam users) and will run some scripts with check for open wikis and for pages with big RCS (spam suspects). We should in any case reduce the load of myxwiki (private cloud analysis shows a big CPU usage) and for this some cleaning up of unused wiki sounds like a plan. We should contact all users and closed unused wikis (I bet there are a lot).
