problem with java aplications

[muzzol]

hi,

i'm having problems with PVE 2.0 that seems to be related to memory. i've found this thread: http://forum.proxmox.com/threads/8195-RAM-and-SWAP-for-OpenVZ?highlight=java

i've followed VSwap instructions, but i can't get a simple application running even whith 8000M memory and 4000M swap.


sometimes application just hangs, and somtimes i get a message like this one:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (nmethod.cpp:1880), pid=532, tid=3077614448

I've attached the java log.

If you want to reproduce, you can use this simple java application: http://sourceforge.net/projects/ksar/

You can launch it with: java -verbose -jar kSar.jar



Please, ask if you need further info. This limitation is very serious for us as we planed to migrate next month to 2.0.

assign at least 2 cpu´s the container and test again. (see 'Resources')

yes!

it seems to work. i'll do some more in deep tests but increasing cpus seems to solve.

is this anywhere in the docs? i think it would be worth to mention it anywhere.

thanks a lot.

there is a lot in the forum, search.

i really did, but seems that i didn't search correct terms.
