Java OutOfMemory exception: mmap error on loading zip file
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.
I also suggested ....
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.

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.tns_admin=/var/ora_net -XX:ReservedCodeCacheSize=512m -XX:+AggressiveOpts -XX:+UseFastAccessorMethods -XX:+UseStringCache -XX:+OptimizeStringConcat -XX:+UseCompressedOops -XX:+UseG1GC -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9026 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
After several time i've got stack trace like that:

Looking to my profiler - everthing is ok (heap and non-heap memory used for 10%) and i have no idea where is the problem.
This problem's happening every day at same time and it's not connected to application uptime. What is cause it problem?
Edited:
New output in log file:
Java HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled. Java HotSpot(TM) 64-Bit Server VM warning: Try increasing the code cache size using -XX:ReservedCodeCacheSize= Code Cache [0x00002aaaab790000, 0x00002aaaad240000, 0x00002aaacb790000) total_blobs=4223 nmethods=3457 adapters=707 free_code_cache=497085Kb largest_free_block=508887936
But i have enough memory: http://i.stack.imgur.com/K8VMx.jpg

Erik over 11 yearsOut of curiosity, how do you figure the Yourkit part?
-
Darya Dmitrichenko over 11 yearsYep, i'm using
yjp-11.0.8
, but the problem happens before i've instaleld it. I'll try to dropG1
collector, but i think it doesn't solve my problem because i work withG1
for the long time. Also i have a problem right now: yjp_out. -
Vishy over 11 yearsI 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

-
Darya Dmitrichenko over 11 yearsYes, I've got 65538/65536. It's problem :). I executed
sysctl -w vm.max_map_count=100000
but i still need to restart my application to apply changes? -
Vishy over 11 yearsI haven't tried this. Once you get the error I would think you should restart. BTW I would also look at minimising the number of mappings as 64K is allot.

Darya Dmitrichenko over 11 yearsThere is a lot of deleted maps there:
cat /proc/26464/maps |wc -l
:65538
cat /proc/26464/maps |grep "(deleted)" |wc -l
:64728
Like that:2aab16919000-2aab1691a000 rw-s 00000000 00:14 25781321 /dev/shm/sem.YmuIm2 (deleted)
Maybe the problem in deleted but not released maps? -
Vishy over 11 yearsI suspect deleted maps cannot be released.

Darya Dmitrichenko over 11 yearsThank you, your answers help me figure out the reason of my problem.
