[jetty-users] Jetty 7 memory leak
|
I am running Jetty 7.1.4.v20100610 on a Linux server with this JVM: Java
HotSpot(TM) 64-Bit Server VM; 1.6.0; 1.6.0-b105; mixed mode
The server will run for a period of time and then run out of memory and
crash. I have bumped the number of file handles so the server can run
longer and I
could get some heap dumps to compare. What I have found is literally
millions of byte arrays hanging around in memory. As you can see below,
it appears to
be related to SSL. I know I am on an older JVM so it could be a JVM
issue but, I found this which could indicate that maybe Jetty is not
shutting things
down properly:

Not quite my exact situation but similar. Can anyone provide some insight?
Hoping the server can last until a reboot tonight....
