[Gluster-devel] Gluster causes fuse to kernel panic

[Bruce]

Hi,

I have been running glusterfs on a server for about 3 days now, and all
of a sudden it has started causing FUSE to kenel panic,

The only information I have is the following stack dump sent via syslog
just before it crashed, It doesn't write this to any of the kernel logs
or anything.

As this causes the system to freeze at the kernel level, I would call it
rather a large bug. If there are any more information I can send which
may help please let me know, however most of the time the system doesnt
get to the point of writing log files.

This occurs on both
gluster at sv.gnu.org/glusterfs--mainline--2.5--patch-459 and a previous
revision I rolled back (unfortunately I cannot find how to get this)
There are also no stale libs or files in the usr/local directory where
the files are installed.

Those who have been in IRC should also know where to get my config files
(look for posts by nzhook)
