[Pvfs2-users] MD server crash

[Kyle Schochenmaier]

I was wondering if this is an expected operation:

I did pvfs2-cp from client to server, ctrl-c'd the client operation, and 
it killed the server.
The client log looks like it handled everything correctly, and 
de-registered all the memory and etc. that it should have done.  Not so 
lucky on the server I think, this is the log from the MD server, which 
is the only one that went down, the Data servers are all still up.

 -- using CVS head from last week, and openIB, client is ppc64, servers 
are x86_64 --

Is this the expected operation when a client 'dies'?  I've seen in the 
past that simply killing the pvfs2-cp process hasnt caused server's to 
go down, but maybe I'm wrong?
