Base on last output, I would start to look on the process that was invoke by ljubica and vmarko, you might find something from there.<div><br></div><div>Anyways, is your server running any DB process? You might also look at the server history on when this problem start to happened and investigate any updates that you or the others have done prior to the problem. SAR command can help. </div>

</div></div>>From the last log it looks like user "ljubica" did something that was<br>
causing his session to crash, then he did something to cause the<br>
server to reboot every hour. I would ask him/her what was done, it may<br>
be operator error on his/her part.<br>
