(Client: SLED11 SP2, 3.0.34-0.7-default x86_64) The "hanging" seems to be caused by the server returning an NFS4ERR_BAD_STATEID(10025) status for PUTFH;LOCK and PUTFH;WRITE;GETATTR calls. The client is making several hundreds of these identical (same filehandle) calls each second. The problem seems to be triggered by (write) actions on an open file when the Kerberos ticket has expired (especially for .xsession-errors and files opened by Firefox or Thunderbird). When (after some time) a new valid ticket is obtained, the kernel reports this error: nfs4_reclaim_open_state: unhandled error -10026. Zeroing state Is this a client or a server problem (and is there by any chance a fix)? Robbert
