[Lustre-discuss] Lustre crashes periodically

Hi everyone, 
I have a problem lately with our Lustre 1.8 deployment. It crashes periodically in a way that the nodes can mount the storage and I can't access the Lustre server machine neither. So I have to manually restart the machine every time to make everything normal again. I tried to see the logs, memory usage and locks count to see whether these issues may have the cause of the problem. But, I don't think they account for this issue.
An interesting symptom I see every time this problem happens is the Infiniband switch network usage lights which blink very fast. I think a huge traffic on the Infiniband network to the lustre server may cause the server crash. Does this relevance seems logical?

Anyway, I hope some of you may have experience this problem before and could help me understand what is happening and how to avoid crashing the server again!

Thanks,
