agents shown in pause

Hi All,
I need help. I have two machines - one with vicidial and one with database and apache. The system runs well but there's something that I don't know how to fix. The version is:
VERSION: 2.0.5-173
BUILD: 90320-0424
The problem is that when the agents log in for a first 5-10 minutes their status is OK. On their pages they click on the resume button and they stay ready for incoming calls. On the admin panel in the real-time campaign summary their status also shows that they are ready. But after around 10 minutes in the admin panel they all are shown as paused. No agent has pressed the pause button.
Can somebody help me or give me an avdice how to fix this?
