we're running LISTSERV-TCP/IP for unix version 1.8b. it crashed sunday morning in (i think) the same place. the core file evaporated so i don't have the exact backtrace. -------- In reply to: Our LISTSERV was down this morning and when I brought it back up it processed a few things and then went down again with the following as the last message: >DMSITP141T Addressing exception occurred at 005473EA in routine LSVBITFD --------------------- -- paul
