Hallo,

this is just for information:

After several (>10) executions of "Reload Server" in layout editor Tomcat shows this error in log:
Java.lang.OutOfMemoryError: PermGen space

Only restart of Tomcat solves the problem.

I upgraded my Tomcat Installation fom 7.0.6 to recent version 7.0.19.
The OutOfMemoryError has never appeared again.

Hi,

the PermGen is the memory in which the classes are loaded. WIth each "reload" your whole web application is reloaded, so new classes are loaded. The permgen has a certain size, if this is full with loaded classes you get the error above.

Ways out:
(.) increase the permgen size (Java VM parameter)
(.) use CaptainCasa Hot Deployment (which we anyway recommend!), then the amount of re-loaded classes is much smaller
