We used to experience something similar to this. A mount appears to hung but eventually succeeds after a long time. We then run portmap service on all the clients and the problem went away. I never realy fully understood why this solved the problem.

I haven't seen it for some years; I recall it used to happen a lot with RHL 5.0, and I don't know when it stopped bothering me.... What's in /etc/exports? Has one of the daemons died? Are you finding .nfs<bla blah> files getting left around? If you're exporting ro, does mounting "-o nolock" help? -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ do not reply off-list ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
