Another possible cause of this problem could be that
a boot was interrupted while in progress. If the IOC
comes up and tries to reuse the same TCP port the
Solaris server sometimes waits a very long time before
it times out the old TCP circuit and begins communicating
with the IOC which is presenting TCP sequence numbers
that are invalid in the Solaris FTP server's perspective.
