[lustre-discuss] operation ldlm_queue failed with -11

[Mohr Jr, Richard Frank (Rick Mohr)]

I think that -11 is EAGAIN, but I don’t know how to interpret what that means in the context of Lustre locking.  I assume these messages are from the clients and the changing “xxxxx” portion is just the fact that each client has a different identifier.  So if you have multiple clients complaining about errors to the same MDS server, then my first guess would be that there is some wrong on the server side of things.
