Hello everyone, We have recently migrated a listserv server to linux/390. At first it appeared to work flawlessly, but it soon began to exhibit strange behavior. Messages will sporadically build in listserv's spool directory and are never delivered. There are entries in the maillog that correspond to each of these messages:
lnxxxxx sendmail[12075]: g6E9B1K12075: lost input channel from listserv.lsu.edu [xxx.xx.xxx.xxx] to MTA after rcpt It looks like sendmail is losing connection to listserv, even though they are on the same machine. There is no discernible time or cpu load pattern for these errors. Our listserv admin is very experienced and has never seen this error before. All of the advice that she has found online suggests optimizing the software in ways that she already has. This has led her to believe that it is an architectural issue, either resource constraints or more esoteric issues. Has anyone out there seen this problem and does the linux/390 platform exacerbate it? Michael Lambert
