Subscriber reboots every two weeks

Hello Experts,

Our subscriber reboots every two or three weeks while the publisher is always up & running. I am looking in the Syslogs using RTMT tool to find out the reason but don't see any messages regarding the reboot. Is there any specific place that I have to look at? Could the switch in which the server is connected be the cause? I really doubt because the publisher is connected to the next port in the same switch but we never had any issue with publisher. What can I do in order to stop the subscriber from rebooting? I am using CCM 5.1.

Take a look to the Application logs along with the System logs and see if something cames up at the time of the reboot.

Re: Subscriber reboots every two weeks

Could it be power related? Does someone come in and clean the Server Room once every two weeks?

I had heard a story from someone (can't remember who) but they had a similar problem and they found out that a cleaning person would come in and dust the server room floor and he ended up brushing up against the wires and it would cause a server to reboot, same time, once a week.

Re: Subscriber reboots every two weeks

i had the same problem with a 6500 we had it connected to a rack mount apc that would run a test every two weeks. are both ccm servers on the same apc if so that rules my theory out.

Re: Subscriber reboots every two weeks

Hello - did you get this issue resolved? We have a similiar problem with our Subscriber rebooting about every 20 days. We are on 5.1 as well. This has actually been going on for about 6 months, with the first reboot happening about 2 months after we upgraded to 5.1 on a new server. We have patched it about 4 times since then, as recommended by TAC. We are here now: and still having the same issue. Only on the Subscriber, the Publisher has been good all along. Thanks!
