Hi all!
I have installed Gentoo Linux with cyrus-imapd-2.3.3+postfix+virtual
domains+mysql. When I connect to pop3 5 or more times, or about 10 or
more client receive his mail, cyrus answer only after 10-30 sec, and
when number of pop3 clients reach 20-30, cyrus completely not respond:
The classic reason I've seen for behavior like this is lack of entropy
leading to blocking reading /dev/random. The easy way to check is strace.
The fix is to use something like rng-tools.
