java.lang.Error: Cleaner terminated abnormally

[CaffeineDK]

Hi Guys/Gals,

We've been experiencing the following error lately and were wondering if anyone could enlighten us about what's happening:

The heap size is 4096M, and looking at the GC output, It looks like an oom situation situation.

But why are we getting a Cleaner terminated error? As far as I can tell there are no oom exceptions of any kind thrown.

What are usual causes for an error like this?

Here are our settings:

debian Linux 4.0 @ 2x quad core Xeon L5420 w/ 8gb ram

sun-jdk 1.6.0.11 (x64 server vm) w/ following options:

-XX:+UseConcMarkSweepGC
-XX:+UseParNewGC
-XX:+CMSIncrementalMode
-Xms4096M
-Xmx4096M
-Xss128k
-XX:PermSize=256M
-XX:MaxPermSize=256M
-Dsun.net.inetaddr.ttl=60
-Dfile.encoding=UTF-8

The only thing I could find remotely relevant is Bug ID: 4938372 (fs) Overlapping mapped files cannot be unmapped (windows), which is from 2003.

I don't see anything here that suggests a oom error except your printed GC statements.

It's throwing an IOException, not a memory error. However, you can download the source code from Sun and see what Cleaner line 125 is to see if it might be related to an oom error. More than once I've had to dig through the java source code to figure out a problem. (I actually had to do this earlier today...oddly enough)

Looking at your messages, Java is calling some external code to access a pipe, which is an OS supported communications queue. The pipe is "broken", which causes the error. Sounds like an OS problem. I'd google "broken pipe".
