This fix is Sun patch 100584-08:
SunOS 4.1.3, 4.1.3_U1
Sendmail causes crashes on SunOS 4.1.3 and 4.1.3_U1. According
to Sun bug number 1077939:

For 4.1.3, this is fixed in patch 100584-08, available on the
Sunsolve 2.7.1 or later CDs. For 4.1.3_U1, this is fixed in patch
101790-01 (SunOS 4.1.3_U1: TCP socket and reset problems).
