Dale,
the logs dont seem to pipoint the exact bug, but in any case the region of
code in which you have hit the bug no more exists in the codebase. Please
let us know in case you come across any other issues.

thanks,

2007/7/10, Dale Dude <dale@xxxxxxxxxxxxxxx>:

linux 2.6.15 (dapper), fuse 2.6.5, dell 2950 w/4gigs.

glusterfs process dies with the below log. Samba is mounted over and
after a few mins of load from 4 different servers the mount dies. There
is no core file. Im not using remote volumes as you will see from the
config. Happens with remove volumes too.
