With some period of time Jenkins start crashes Java machine. It's happens 2-10 minutes after start.

I've tried:
1. Run Jenkins from Tomcat 5
2. Like a sudo daemon
3. Like a simple java app
4. version 1.492, 1.494
5. No any additional plugins

I've tried use
1. Sun Java
Linux safephone_development3 2.6.18-308.11.1.el5 #1 SMP Tue Jul 10 08:48:43 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
2. Open JDK
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.10) (rhel-1.28.1.10.10.el5_8-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

I attached some logs that I've could get.

About configure Jenkins:
I have master on CentOS, and two slaves on Win and Mac. And i have 12 configured projects. But only 1 executor on each node.

No any entries in /var/log/messages, dmesg. It's just crashes java.

I saw a few topics with the same problems but no one says what it is and how fix it. Please help me.
