Has anyone seen behavior like this? We have a Compaq Systempro running ISC 386/ix 2.0.2 [System V 3.2]; it serves as our central mailhub on a thin-ether network. We are trying to bring some Sparcstations into the picture, but every time they make a connection on the SMTP port [port 25 in the default ISC TCP/IP setup] they refuse to drop it when the actual mail transaction is completed. After one or two hangs in this manner the Systempro refuses to open any additional SMTP ports, and mail services effectively grind to a halt. Running a sendmail stop/start sequence [/etc/init.d/sendmail stop, /etc/init.d/sendmail start] clears everything out, but this strikes me as a very nonoptimal solution. [I can't check the Systempro every hour to see if things need to be cleared, and turning a cron loose could result in some messy mailus interruptus....:-)] If anyone has any notions, please post or email. I'll summarize results if we get this thing fixed..... -- <:> Dean Riddlebarger "The bus came by <:> <:> MIS Manager - Truevision, Inc. and I got on, <:> <:> [317] 841-0332 That's when it <:> <:> uucp: uunet!epicb!dean dean@truevision.com all began." <:>
