[Gluster-users] Issue with Samba over Gluster

[Irshad Ahmed]

Pavan,

As i said before that i cannot switch to gluster 3.0.5 as most of my
applications dont work properly in 3.0.5 so i am giving u all the info
required using 3.0.4 version.
I used to get the same issue with 3.0.5 also with samba.
Here are the trace logs : http://dpaste.com/217973/
I have attached core dump file.
Please have a look and reply.
