Peter Anvin, Arun Sharma, autofs, nfs Don't know if it helps, but we also run a few hundred autofs4 clients, with a mix of 2.4.21 and 2.4.18. The 2.4.21 machines are seeing quite a few of these messages, but not on the 2.4.18 machines. We haven't seen any of the oopses described below, though. -matt On Mon, 15 Sep 2003, Ion Badulescu wrote: > On Mon, 15 Sep 2003, H.

I haven't tried to reproduce it with your method, but I do see the bug; no oops though. /fc ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ NFS maillist - NFS@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nfs ^ permalink raw reply [flat|nested] 2+ messages in thread
