Index Cluster Device Fails

Hello,

I've been experiencing issues with the OVA Template for Enterprise Manager syslogng virtual machines.

1) I have request logging enabled from my LTM that forwards syslog traffic to the index cluster I configured using Enterprise Manager.

2) I have 3 devices in the index cluster taking on syslog traffic from my LTM

My symptoms are that spontaneously they stop receiving syslog traffic. I am unable to query requests in Enterprise Manager.

To fix the issue I simply just restart the index cluster devices through VMware. This temporarily fixes the issue. Also going in and doing ifcfg down/up on the Traffic interface resolves the issue.

I am wondering if anyone has experienced this... It is happening on all three devices in the index cluster.
