Java OutOfMemory exception: mmap error on loading zip file

Question

I run my app on production env (rhel 5.2 x64, oracle jre 1.7_05, tomcat 7.0.28) with JVM arguments:

-Xms8192m -Xmx8192m -XX:MaxPermSize=1024m 
-Doracle.net.t         


        

Answer 1

I have seen these error before when running out of resources such as running out of swap space or running out of allowed memory mapping. Have a look at sudo cat /proc/$PID/maps | wc -l compared with cat /proc/sys/vm/max_map_count

See comments below.

You appear to have run into a bug with YourKit. What version are you using?

I would cut down most of your options as they either are the default and don't do anything or could be complicating matters.

-mx8g -XX:MaxPermSize=1g -Doracle.net.tns_admin=/var/ora_net 
-XX:ReservedCodeCacheSize=512m -XX:+UseG1GC -Dcom.sun.management.jmxremote.port=9026

I would try dropping -XX:+UseG1GC as well as this is a relatively new collector and shouldn't change your results.
