Have a problem on a V5R2 machine where the SMTP server keeps crashing. Here's the info I found in the job log: MCH4401 Escape 40 11/13/03 06:07:29.543216 QTMSMTPT QTCP 0F6E QTMSBRSR QTCP *ST To module . . . . . . . . . : QTMSAUTO To procedure . . . . . . . : autoregistration Statement . . . . . . . . . : 433 Message . . . . : Return instruction not valid. Cause . . . . . : An invalid use of a return instruction was detected. A Return From Exception instruction ran in an invocation not defined as an exception handler, a Return External or Transfer Control instruction ran in an invocation defined as an exception handler, or a Transfer Control instruction ran in an invocation defined as an event handler. Anyone have any ideas what may be happening here? This is quite a pain.
