any and all suggestions. Please see below for details. We recently upgraded to a new hardware platform, and started having issues immediately with Broken pipes and I/O flushing.

notfind ansatisfying answer.i ran qpopper 4.0.4 on linux 2.4.18no ssl, mysql or any other "special" enabled. just simple pop3.sometimes the log shows:popper[]: I/O error flushing output to client blah at blah [blah]:Operation not permitted (1)what does this really mean, http://qpopper.pensive.narkive.com/Xm1GUCXc/i-o-error-flushing-output-to-client and when will it occur?i dont think it´s just some network connection troubles...or is http://stackoverflow.com/questions/8053824/ssl-broken-pipe it?thanxMK Daniel Senie 2002-05-16 13:54:02 UTC PermalinkRaw Message Post by Martin Kellermannhi all!i searched already alot concerning the following qpopper error, but didnot find ansatisfying answer.i ran qpopper 4.0.4 on linux 2.4.18no ssl, mysql or any other "special" enabled. just simple pop3.Operation not permitted (1)what does this really mean, and when will it occur?Client (remote i/o error machine) closed the connection, qpopper tried to write tothe socket, but the TCP session was already closed by the kernel on theserver in response to the close from the client.Post by Martin Kellermanni dont think it´s just some network connection troubles...or is it?See if your client gave up.

That's the usual cause.something else:can i suppress the "-ERR POP EOF or I/O Error" (that occurs, for examplewhen client telnets port 110, logs in and then kills telnet session withoutlogging out) without patching the sources?some of my clients are using a "broken" mailer software that behaves likeexplained, and my logs are full of " -ERR POP EOF or I/O Error"...thanxMK Randall Gellens 2002-05-20 23:30:31 UTC PermalinkRaw Message Post by Martin KellermannPost by Da
