Hi ! Thanks for the reply. Its good(??) to know that I'm not the only one facing the problem. ;)
BTW, what nfs client are you using? The mounting options you provided doesn't seem to exist on my linux client. What does the options below mean? -b -I -T -3 A search at google reveals similar problem faced by other guys (though theirs is not qmail/vpopmail based). Most of them attribute it to network congestion ... Some say the problem goes away when they upgrade their networking components (switch, nic, cat 5 cables etc ..) I will be getting a better dedicated switch and expensive network cables ... Will let you if that solve my problems.

Can you guide me on what is > the best mount options that I should be using? And what values for rsize, wsize are you all using? I get the same thing. I've spent days trying to track it down. It doesn't seem to cause problems, but it's terribly annoying. The mount options I use are rw,-b,-i,-T,-3,-r=8192,-w=8192, but I'm using jumbo frames so most requests should fit in a single packet. --Doug
