Subject Re: Tomcat 4.0.x memory leak (not javac)
Date Tue, 11 Nov 2003 07:49:03 GMT
I am also facing the same problem of memory leakage. I have posted on mail about this on 19th
Nov too... 

I had contacted to the support people where our web application is hosted. I had got few suggestions.
According to their suggestion - 
1. I increased the heapsize in file.
2. I have also tried to increase the file descriptor size.

Increaing the file descriptor size helped me at some extent. It stopped the frequent exceptions
in Tomcat -> catalina but occasionaly I am still gettng same exceptions.
I would really like to have some more suggestions.

  I found it once but I can't find it again.  I was pretty sure I entered 
  "memory leak" in the summary field and came up with results, but it 
  doesn't work now.

  Anyhow, the javac bug is referenced in the release notes of 4.0.x.  I 
  don't think it's a javac bug but a tomcat bug with the interface into 
  the javac classes.  After all, it's not referenced in the release notes 
  for the newer versions of tomcat.
