Description: Hi, all.
I found that there are so many opened sockets in LMTP daemon. I think they are not closed properly and remained continuously. Here is the lsof's result. Is this a some kind of leak of socket? dbmail-lm 3833 nobody 14u sock 0,6 0t0 29164757 can't identify protocol dbmail-lm 3833 nobody 16u sock 0,6 0t0 29165680 can't identify protocol dbmail-lm 3833 nobody 18u sock 0,6 0t0 29165696 can't identify protocol dbmail-lm 3833 nobody 21u sock 0,6 0t0 29164781 can't identify protocol dbmail-lm 3833 nobody 23u sock 0,6 0t0 29164783 can't identify protocol dbmail-lm 3833 nobody 24u sock 0,6 0t0 29164784 can't identify protocol dbmail-lm 3833 nobody 25u sock 0,6 0t0 29164785 can't identify protocol dbmail-lm 3833 nobody 26u sock 0,6 0t0 29164786 can't identify protocol dbmail-lm 3833 nobody 30u sock 0,6 0t0 29165702 can't identify protocol dbmail-lm 3833 nobody 32u sock 0,6 0t0 29165704 can't identify protocol .... .... ====================================================================== ---------------------------------------------------------------------- (0003221) paul (administrator) - 09-Aug-11 09:50 http://dbmail.org/mantis/view.php?id=913#c3221 ---------------------------------------------------------------------- Check again. Those are most likely the unix-socket connections to the database backend. ---------------------------------------------------------------------- (0003222) superkkt (reporter) - 09-Aug-11 10:00 http://dbmail.org/mantis/view.php?id=913#c3222 ---------------------------------------------------------------------- No, it's TCP socket used as LMTP session and I also found that the sessions received RSET command from Postfix MTA are not closed and remained continuously. Postfix sometimes sends two mails using RSET command on the same LMTP session, but it does not send QUIT command after '.' of DATA command. Is this a normal situation? ---------------------------------------------------------------------- (0003223) superkkt (reporter) - 09-Aug-11 10:21 http://dbmail.org/mantis/view.php?id=913#c3223 ---------------------------------------------------------------------- sorry, it's my mistake. The problem is that Postfix doesn't send anything after RSET command sometimes, so the LMTP session is remained continuously. I think it's not a dbmail's problem, but I don't know why Postfix do this and the socket timeout didn't works.
