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). Log (syslog) said nothing what caused this problem and didn't even give any hint. Best regards, ++Titus
