RedHat 6.1 with qmail-1.03 and ucspi - 0.84.
qmail-smtpd is run by tcpserver and the -c value is 2000. But as soon as
it reaches 1247 sessions, it is not able to fork further processes, the
error message is:
tcpserver: warning: dropping connection, unable to fork: temporary
failure
This value (1247) does not change even when I increase RAM from 512MB to
1GB or decrease it to 128MB. My question is what causes fork to not run
a new process. I know it is a non qmail question. But someone over here
who has already solved this problem may help me or point me to some URLs
to troubleshoot this.
Thanks.
