Hello all,

I have Postfix 2.5.1 running on Solaris 10 SPARC. The problem is that smtpd
daemon crashes occasionally. Some core dump related information is placed
below.
Probably the cause is non-null-terminated string somewhere? I understand
that the reason isn't probably Postfix, but Solaris; anyway, has anybody
seen this bug before or can tell something about it? I can't found anything
related in Solaris bugs description or google.
