Hello toaster friends!

This week I experienced a very strange NFS performance in our POP3 servers. We've 4 POP3 Linux clients mouting 2 netapp boxes, like this:

/var/spool/mail1 - F760 (cluster) /var/spool/mail2 - F760 (cluster) /var/spool/pop - F720

Our Linux clients are Pentium III 650Mhz Dual with 1GB RAM running a Red Hat-like distribution with Kernel 2.2.14-19smp.

This solution has worked very fine until this week, when we started experiencing high Load Average in our Linux boxes and accumulation of pop processes.

Copies from /var/spool/mail to /var/spool/pop are verrrrrrrrry slowwwwwwwwww... so pop processes get status of "D" (Disk Waiting right?, and caos takes place.

I don't know what it is. We're crazy here...

Anyone has ever had hard times like this before with Linux?

Thanks a lot for any help!!!!!!!

PS: We've Brazilian NetApp guys giving us a hand here.
