Hello,
a couple of weeks ago I submitted an issue I had with qlogin/qrsh ... which
turned out to be caused by a quota restriction I had forgotten about.
I do however observe a sporadic issue with qlogin/qrsh ...
$ qlogin -l h=gpu-v100

Are all nodes connected in the same way to the machine you issued the `qlogin`
on? Is the firewall setting identical on all computing nodes?

qrsh behaves the same except that it is silent.
If I try a different node, I get success, which suggetss it is perhaps a
configuration issue but I just can't get my head around it - any ideas on how
to troubleshoot this ? Or perhaps someone on this list has already faced this
issue ?
PS - just to be sure I disabled all quota restrictions
no firewall on the nodes - they're on a private subnet.
I do otherwise observe some network lag for that particular system (and another
for which I have the same issue). I'll find the cause for this and try again
once the lag has been resolved.
This lag is perhaps causing a timeout for the qlogin connection ?
