It’s a large processing farm, using LSF. I’m nor seeing those disconnects anywhere else on the storage system, just from the LSF farm…Not sure of the workload at the time it striated, I’ll ask the HPC guys if they can point me at some info.

That means that an NFS client ceased responding to inbound network traffic for a long time, and eventually ONTAP closed the transmit buffers down entirely.
What is the workload on your end servers? The only time I’ve seen this issue occur, other than an actual total failure of network connectivity, is with some Oracle DNFS bugs.

Hi all, I have an issue with a FAS3170 and NFS. Seems that hosts are being disconnected and the only thing I can find is a strange message that would seem to point at TOE? :-
Tue Mar 4 21:13:49 GMT [netapp5a: nfsd.tcp.close.idle.notify:warning]: Shutting down idle connection to client (172.17.82.34) where transmit side flow control has been enabled. There are 22 outstanding replies queued on the transmit buffer
However, TOE is turned off. If someone could point me in the right direction, it would be much appreciated :)
