Hi
I'm having a cluster of two pop3 servers using vpopmail+qmail. My monitoring
program is mon, because I've a LVS solution.
Sometimes, I have mon reporting false alarms about pop3 login on just one
server: with "false alarm" I mean an alarm about the pop3 server at first
attempt and an ok situation at second one. Controls are done every minute.
The monitoring program (written in perl) is doing:
telnet server port
HELO monhost
quit
My logs about the pop3 program show no problems even when I've got the error
(i'm sure about the event because all machines are syncronized with ntp):
2001-06-06 10:53:14.759320500 tcpserver: status: 1/50
2001-06-06 10:53:14.759856500 tcpserver: pid 20437 from monitor
2001-06-06 10:53:14.759990500 tcpserver: ok 20437 servername:serverip:port
:monitormachienip::port
2001-06-06 10:53:14.768756500 tcpserver: end 20437 status 256
2001-06-06 10:53:14.768840500 tcpserver: status: 0/50
I tried to sets timeout to 5 seconds but (1) doesn't solve the problem, (2)
makes no sense cause the telnet from the monitor machine is <1 sec.
What can be the problem? TCPSERVER isn't spawn a qmail-pop3 well or there
can be other problems?
