OBA desktop website hangs and becomes unresponsive from the user's perspective at the browser #10

Closed barbeau closed 11 years ago

barbeau commented 11 years ago

This seems to be a problem with XWiki, as the OBA mobile web sites work fine, which are hosted in the same onebusaway-webapp WAR file on Tomcat. API seems fine as well, as Android app was working fine.

After remote desktoping into the server, I shut down XWiki using:C:\OneBusAway\XWiki\XWiki_Enterprise_4.2\stop_xwiki.bat

However, the black command prompt output window for the running XWiki instance didn't disappear, although the running java.exe did seem to terminate. When I started XWiki via: C:\OneBusAway\XWiki\XWiki_Enterprise_4.2\start_xwiki.bat

...a second black command prompt window opened, and gave the below error:

Upped memory in start_xwiki.bat today to:

set XWIKI_OPTS=-Xmx1024m -XX:MaxPermSize=128m

So, we'll see if that has any effect.

barbeau commented 11 years ago

Haven't seen this problem again yet, and the site seems generally much more responsive after upping the XWiki -Xmx argument. We're closing this for now, although if XWiki memory requirement increases per user this may need to be revisited as site traffic increases.
