<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Alan, <p>On a client running all by itself on our production network overnight, doing an "ls -lR /usr" and doing a compile (in a loop) is giving the same problems. <p>A little snipit from /var/log/messages <br>Nov 10 04:31:20 spc81 kernel: nfs: server student OK <br>Nov 10 04:33:17 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:33:17 spc81 kernel: nfs: server student OK <br>Nov 10 04:34:59 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:35:04 spc81 kernel: nfs: task 20823 can't get a request slot <br>Nov 10 04:35:35 spc81 kernel: nfs: server student OK <br>Nov 10 04:35:35 spc81 kernel: nfs: server student OK <br>Nov 10 04:44:43 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:44:44 spc81 kernel: nfs: server student OK <br>Nov 10 04:45:56 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:46:00 spc81 kernel: nfs: task 20457 can't get a request slot <br>Nov 10 04:46:00 spc81 kernel: nfs: server student OK <br>Nov 10 04:46:03 spc81 kernel: nfs: server student OK <br>Nov 10 04:49:15 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:49:15 spc81 kernel: nfs: server student OK <br>Nov 10 04:49:25 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:52:21 spc81 kernel: nfs: server student OK <br>Nov 10 04:53:43 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:53:43 spc81 kernel: nfs: server student OK <br>Nov 10 04:54:01 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:54:02 spc81 kernel: nfs: task 64822 can't get a request slot <br>Nov 10 04:54:13 spc81 kernel: nfs: server student OK <br>Nov 10 04:54:15 spc81 kernel: nfs: server student OK <br>Nov 10 04:55:57 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:55:59 spc81 kernel: nfs: task 29484 can't get a request slot <br>Nov 10 04:56:21 spc81 kernel: nfs: server student OK <br>Nov 10 04:56:23 spc81 kernel: nfs: server student OK <br>Nov 10 04:58:15 spc81 kernel: nfs: server student not responding, still trying <br>Nov 10 04:58:21 spc81 kernel: nfs: task 1477 can't get a request slot <br>Nov 10 04:58:52 spc81 kernel: nfs: task 1478 can't get a request slot <br>Nov 10 04:59:15 spc81 kernel: nfs: server student OK <p>Shows that under no (or little) load this thing is failing. <p>We have 20 networks with ~100 machines on each with this same problem. Only a few at a time are using Linux. We are trying to promote Linux as a great operating system, but this is not helping. Again the samba on win95 is puring along nicely plus every other service but for NFS. <p>We have changed the NIC on this server to 3Com 3c90x for no change in status. Clients are using CNETPro120 200 and Intel eepro100 <p>The servers are generally PIII500 512MB RAM. <p>We have tried mount flags rsize=1024, 8192, 128, with no change. <p>It looks like a server issue related to RPC. But I am only guessing here. <p>Any more help is much appreciated. <p>Thanks <p>Grahame Jordan <br> <p>Alan Cox wrote: <blockquote TYPE=CITE>> By the evidence that we have gathered it seems that the Server is not <br>> taxed too much as samba users are getting files OK etc. The can't get <br>> request slot is plaguing many others in different ways.
