Description _ rkubacki 2005-01-04 17:13:18 UTC 
dev build from Jan 4

I have a simple web module that I repeatedly
redeploy to running Tomcat instance. During this
the usage of permanent generation memory grow with
each redeploy. Most likely some Ant task is
leaking here and blocks unloading of classes from
memory.

The result will be OutOfMemoryError when the size
of permgen reaches 64MB.

probably similar to issue 52846
Comment 2 _ rkubacki 2005-01-05 12:41:38 UTC 
Now it seems that 50MB is enough and it is not growing too much above
this limit (or can be GC'ed later). I did ~100 redpeploys usualy
together with some change in JSP or Java source. I will close the bug now.
