Pix pair failing over/back multiple times per day

Hello,

I have two Pix 515Es in a failover configuration. The pixes are running 6.2(2). We have an issue where the primary will fail to the secondary and then later the secondary will fail back to the primary. This issue sometimes is happening 2 to 3 times per day. Both Pixes do not report having been powered off at all but the error reported is a power failuere. Does anyone have any suggestions as to the cause of this issue ? Logs from the last failover are included below:

Re: Pix pair failing over/back multiple times per day

Hi .. I suggest you checking:

1.- Status of all monitored interfaces is UP. An interface might be flapping.

2.- The power sources where the PIXes are connected. It could be an electrical issue providing causing unexpect voltage changes.

I hope it helps .. please rate if it does !!!

Re: Pix pair failing over/back multiple times per day

1. As far as I can tell they are all up (as per the logs above) and nothing indicates a flap in the logs. I forgot to mention that we are using stateful failover via a cross-over cable on intf5. Because we are using stateful failover the uptime information is copied between firewalls, making it difficult to determine whether there has actually been a power outage.

2. I currently have the primary Pix powered off and am running on the secondary. If we have an outage in the next 24 hours we will be able to determine if the issue is power related. If there is no outage then the issue is probably the primary Pix as it reset yesterday when the secondary was powered off.
