OutOfMemoryError: PermGen space

[mkieboom]

Hi there,

Within our company we have Alfresco running within VMWare for a few months now however still we have problems with Permgen space error from Java.
The error occurs every 2 or 3 days while the virtual machine is definetely powerfull enough to run Alfresco.

I can not find any website or blog with the right solution to the problem.
Can anyone help me with this problem? The wiki from Alfresco also did not give me the right solution.
http://wiki.alfresco.com/wiki/ASR_Performance_Optimization

Kind regards,


Marcel Kieboom

[mrogers]

Nothing.   Its not a problem.

[maheshma]

Thank you for your reply. but when we are getting the Error "Still busy" we are unable to run the application and  We are left with no option  but to restart the application every time we encounter this issue, Can we have the any other solution?

Thanks in advance. Hope to hear from you soon.

With Regards
