Argh, just found out that it is not the polling.
Even without the polling, the ssh-tunnel connection
gets disrupted, although not as frequent as with
the polling. Possibly, the polling makes the problem
more visible, but it not the culprit.
My apologies for the noise.
I don't know yet exactly what it is. I use a script
to test whether the ssh-tunnel is still alive; if
not, then the tunnel is renewed. This script has
worked like a charm for almost 6 months.
Don't know what's has changed in the meantime.
Also, four PCs are part of this ssh-tunnel, which
makes it rather complex to pin-point the problem :(.
Anyway, that's my problem.
Most important: the xl polling seems OK.
Meanwhile I have learned a lot more about what
polling actually is!
Thanks,
Rob.
