[Shfs-devel] shfs oops

[Pascal A. N. <pas...@ip...>]

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 kervel 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

PS: Hope cross-posting to both lists is ok.
