what operating system are you running? not all systems support TCP_NODELAY equally. If a system has poor TCP_NODELAY support, i would imagine it could cause this behavior.

Paul TheodoropoulosHello all, I have a strange problem with tcpserver and the pop3 daemon.The short story: When I start the pop3 daemon through tcpserver with the -D flag the daemon refuses to die when I run svc -d /service/qmail-pop3d. Without the -D, the pop3 server is extremely slow and is serving only 3-4 messages per second. The long story: tcpserver refuses to die using svc -d /service/qmail-pop3d when the startup script looks like this: #!/bin/sh tcpserver -H -R -D -lmail.yourplana.com 0 pop3 \ /var/qmail/bin/qmail-popup mail.yourplana.com \ /home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir 2>&1 If I try to start the pop3 daemon again with svc -u /service/qmail-pop3d I get the well known "tcpserver: fatal: unable to bind: address already used" error message. To kill the tcpserver I have to run 'lsof | grep tcpserver' and then kill the pid of the tcpserver -OR- just 'killall tcpserver'. Then I can start the pop3 daemon through tcpserver again. When I'm using this startup script I' having no start/stop problems, but the pop3 daemon is terribly slow and hands out only 3-4 messages to the client per second: #!/bin/sh tcpserver -H -R -lmail.yourplana.com 0 pop3 \ /var/qmail/bin/qmail-popup mail.yourplana.com \ /home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir 2>&1 Please note that the only thing changed here is the tcpserver startup flags. The first startup script has the extra -D and won't die, the second one is without the -D flag and is terribly slow but dies nicely. All the -D flag does is telling the tcpserver not to delay sending data, so I can't imagine why it becomes a problem when stopping the tcpserver. Any ideas? Thanks, -- Erik
