Tomcat 5.5-7 hangs on proxmox's pve kernel

[ArtemZ]

Hello,
I recently discovered that apache tomcat (all actual versions) hangs on 2.6.32-pve kernel when running in openvz container. It works normally with usual openvz kernel.

There is it's log:

[root@test logs]# cat catalina.out

Where to look to get it solved?

Looks like I fixed it by installing 2.6.32-5-openvz-amd64 kernel from debian on host.

Assign more than one CPU to your container.
