Hello,
alas I get not response to my question, but some more googling and =
testing leads to a solution.
With the following mount options all runs well:
tcp,rw,bg,dumbtimer,-r=3D32768,-w=3D32768
the most important thing is to not use any of the following
intr or soft
it seems (only idea and wild speculation), that with even the intr =
mount option some IO ops are interrupted, so that I see the reported =
errors below.
Perhaps the problem are a signal send to a thread???
Regards
Lars
