Terminating Database along with its Oracleservice (Win2008R2sp1)

Question

My database terminated silently (nothing in logs) along with its Oracleservice everytime update run that performed via database link. When this update performed locally - nothing wrong happens.
Works flawless on test environment with the same software and hardware.
Here - EXPDP Terminating Database along with its Oracleservice (WIN 2003k ) - removing antivirus helped. But in my case no antivirus on the server. And a lot of memory and processors.
On client side error "ORA-03135: connection lost contact" appeared. I tried to run quiery via database link from diffrent servers, including other database on the same server.
Please, give any ideas.
