#41 Crash / oops

[Pascal]

Hi !

I am using shfs (CVS version from August 17, 2005) and am
generally quite satisfied.

However, shfs crashes regularly (after some time of use,
e.g. an hour or so).

System used: SuSE linux 9.3, uname -a gives kernel
2.6.11.4-21.8-smp #1 SMP

I also get the messages below in /var/log/messages:

Is there a way I can resolve this problem, or provide more
information that may help to fix it?

Pascal
