Could you build & install a debug (-g) version of rpc.rquotad,
attach to it with gdb while its running, then repeat the above
and send the stack trace & any other interesting info gdb will
give?  I don't have access to any Sun machines, but I know that
these combinations of client<->server work, and are tested:
  Linux<->Linux
  IRIX<->Linux
  Linux<->IRIX

I assume this same problem will happen with ext2 quota (could
someone confirm that?) - Jan, have you seen this issue before?

[Jan - the mail thread is available here...
http://oss.sgi.com/projects/xfs/mail_archive/0107/msg00730.html
although I'm unsure whether or not the original problem involved
a Sun machine]

thanks.
