Hi,
Today our mailserver jammed all its pop3d processes and trace said "read(10," and it was blocking there.
imap-processes were served fine and db-files were ok (DB4).
Then I restarted all processes and checked db-files and tried to debug.
Then I was desparate and I restarted whole system and after init everything was fine again (pop3 was served without that jam.)
[EMAIL PROTECTED] titus ~%> telnet 0 110 Trying 0.0.0.0... Connected to 0. * Hanging here (waiting banner) * Escape character is '^]'. ^] telnet> quit Connection closed.
^ No banner even.
Imap(s) (working fine, banner prints)
Escape character is '^]'. * OK foo Cyrus IMAP4 v2.1.11 server ready
Authentication and all operations worked fine on imap's side.
I just wonder what caused this kind block in pop3-processes or what _could_ cause this kind problem..
Kernel: 2.4.18-14 / GNU Linux I am using PAM (via saslauthd) for pop and imap.
No, I didn't check if I was out of entropy (random).
This is most likely your problem, since the pop3d banner includes a random challenge for APOP.
