I'm using coda on one machine running FreeBSD whitch is both server
and client. A few days ago I put my mailbox (qmail's Maildir/ format)
on a coda volume.

Since then there are several problems (not connected with qmail).

Each process whitch tries to access /coda directory hangs on
"coda_call". Sometimes I can manage to interrupt such a process with
"Ctrl+C", and then I see something like this:

coda_call: tsleep returns 4 cnt 109
	   siglist=2 sigmask=2 mask=2

Here is a part of my SrvLog:
16:41:00 ViceValidateAttrs: (1000001.c54.78d) failed ()!
16:41:00 ViceValidateAttrs: (1000001.c58.78e) failed ()!

What should I do to bring my server back to work?
