This
particular issue happens with both 7.1.4 and 7.1.6. We were attempting
to upgrade to 7.1.6 to see if it fixed the issue but it has not. Of
course, you saw my other post with the high utilization issues so it
has been a battle.

Tony,
From your other posts, you seem to be upgrading to 7.1.6 - can
you confirm whether this is happening also on 7.1.6 or only 7.1.4?
thanks

I am also seeing this same issue with the
1.6.0_21 JVM on a 32 bit Linux
server so it is not because of the older JVM. I still need some help
with this one.
Thanks

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....
