That could be, though the trace also shows it falling back and retrying,
and in that case (packets 8 & 9) the gap is only 7 seconds and the
behavior is the same.

More likely is that you're running into an offer problem which isn't
shown directly by this snoop trace, but known; it's CR 6220012 and for
Solaris 9 SPARC you should try patch 112837-09.
