Hi,
I'm running one grails portlet on liferay 5.2.3 successfully, now i developed another grails portlet and hot deployed, but the portlet showed me some errors and not working says "portlet is temporarily available" .
I tried restart server but still only one portlet is running and other is not running .
This is the log when deployed another portlet (log cropped).
