[Bug 416091] New: lockd/rpcbind spamming /var/log/messages
https://bugzilla.novell.com/show_bug.cgi?id=416091 Summary: lockd/rpcbind spamming /var/log/messages Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: jnelson-suse@jamponi.net QAContact: qa@suse.de Found By: --- 2 machines, 1 NFS server, 1 NFS client. NFS client rebooted /many times/ (over a dozen in 1 day) NFS server spams this, every few minutes, into the logs until SuSEfirewall is taken down on client for a few minutes (presumably to get a different response) 1595 lines of in a bit over 12 hours. Aug 9 22:38:56 turnip kernel: lockd: server worklaptop not responding, timed out Aug 9 22:38:56 turnip kernel: rpcbind: server worklaptop not responding, timed out It looks like if I had not thought to temporarily shut down the firewall that the server would have continued to do this indefinitely. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is called a "GRANT callback". The GRANT callback should not be retried indefinitely - there is no need. If the client is still interested, it will ask again in a little while. It is interesting that you are getting a "timed out" message rather than a "still trying" message - yet obviously it is still trying. That suggests that the retry is higher up the stack - probably in lockd, not in the RPC layer. The fact that shutting down the firewall stopped the messages suggests that your firewall is rejecting the GRANT callback. This could be seen as an incorrect configuration which possibly should be fixed. Questions: 1/ What are your firewall settings? Is it just the default provided by the opensuse installer, or have you adjusted it at all? 2/ Has this come back at all since you restarted the firewall? It could be that you just get a few of these messages each time the client tried to get a contended lock, and maybe it was doing a lot of locking? Suresh - would you be able to look at this? Maybe try to set up a firewall which discards the GRANT callback, and see how the server responds? Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It has not come back since then. It appeared to me that, basically, the messages were gonna continue forever because the firewall was blocking them (I had rebooted that box a few times). As soon as the firewall let them in (presumably to be rejected) the messages stopped and did not come back. It was doing a lot of locking. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I tried multiple times(with 2 11.0 boxes, one as client and another as server) with the test program above, but couldn't reproduce. Looks like it's a hard to hit one. I see no NLM_GRANTED callback though I see other NLM calls.. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'll try to reproduce the problem at home. If you don't see NLM_GRANTED it's possible the (server) firewall is denying the traffic. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
