Tech Support suggested I drop a note to the list about the problem I am facing. After upgrading to sendmail 8.12.8 I noticed a slowdown of jobs being processed by listserv (lsv). The communication between sendmail and lsv seemed to be OK. ie items were being passed between them for the most part. What I saw was at time lsv would send a job to sendmail and just hang. lsof showed that lsv was sitting on a asdf.mail file. truss of the lsv process showed "sleeping". sendmail showed getting the list and sending it out. the lsv log output showed the addresses going out, but never said "11 Mar 2003 12:25:23 Done - 1 outbound file (3 rcpts)." Only after restarting lsv did things get going again... for a while. jobs started backing up, ie asdfasdfasdf.job files in spool. after backreving sendmail to 8.11.6, the spool cleared and has not backed up since. We need to upgrade to sendmail 8.12.8. Any ideas?? FYI: sendmail.cf is generated from sendmail.mc file and we have tried running sendmail in both modes. ( with and without submit.cf ) our sendmail.mc file was modified to handle a TLS option field otherwise it is the same for 8.11.6 and 8.12.8 Thanks Brian K. Becknell Clemson University
