Re: [Gluster-devel] GlusterFS clients getting disconnected from servers with signals 6 and 11

[Krishna Srinivas]

Ioannis,

Can you make server and client of same version and see if it segfaults?
If it still segfaults, can you tell us what the trigger to the crash is? what
were you trying to do? If you can get the gdb backtrace that would help
too. "gdb -c /core-file <path to glusterfs>"
