Hello,

We have several NAS servers with kernels 3.4.xx-3.13.xx. We've got a
problem: after 1..4 months of work target servers stops responding to
login requests.

I have seen a very similar problem on file servers, in my case an NFS workgroup server. I thought it was due to down level 3.8.13-fc17 kernel, not scheduled for upgrade for a few months yet, probably over Labor Day weekend.

However, existing connections on the machine also will respond to ENTER with a newline, but any connand requiring a new process hangs. It behaves as if the machine was out of processes, but I traced processes every few minutes and saw no buildup.

In addition, the machine hosts a virtual machine which continues to work just fine. Does any of this match additional issues you didn't mention or haven't checked?

Any ideas?

May or may not be related, we have a console open on the machine and can verify the odd behavior.
