I still think there is bug in 5.5.30-30.2, because with previous version server was running fine.

2013-04-18 in the morning I added 4Gb ram to the server. Still after 24h server started to swap:

Also I have attached Temporary Object graph for one month. There is no significant increase in created tmp tables, so I think that this increased memory usage is because of mysql version.
