[Gluster-devel] mainline--2.5--patch-267: rm -rf signal 11

[Krishna Srinivas]

Gerry,

I am trying to reproduce the prolem here. Can you give me
any clues? what were you trying to do? was it a plain "rm -rf"
or were you doing simultaneous rm -rf from the same
mount point?

I am assuming that your setup is an afr connected to four protocol/client.
Correct me if I am wrong.

Thanks
Krishna
