Package: xinetd
Version: 1:2.3.13-3
Severity: important
xinetd handles plenty of pop3s here. it has the "cps X Y" setting, limiting
connections per second, and deactivating service if overloaded. THat's fine.
xinetd seem to unbind the port. this is not really good, because:
May 21 12:43:23 host xinetd[9622]: EXIT: pop-3 status=0 pid=5457 duration=0(sec)
May 21 12:43:23 host ippl: pop3 connection attempt from 555.444.197.510
May 21 12:43:23 host xinetd[9622]: Deactivating service pop-3 due to excessive
incoming connections. Restarting in 4
seconds.
May 21 12:43:23 host xinetd[9622]: FAIL: pop-3 connections per second
from=555.444.197.510
May 21 12:43:25 host ippl: port 19730 connection attempt from 555.444.196.3
May 21 12:43:26 host ippl: pop3 connection attempt from 555.444.198.586
May 21 12:43:26 host ippl: pop3 connection attempt from 193.151.116.531
May 21 12:43:27 host xinetd[9622]: bind failed (Address already in use (errno =
98)). service = pop-3
May 21 12:43:27 host xinetd[9622]: Error activating service pop-3
at that point xinetd have given up pop3 port. for ever, it seems, since
even reloading (HUP) doesn't get it again. restart is needed.
I don't know who and how got the port (occasional enough not to be able to
reproduce and customers are angrier than let me play with it), but would
be nice not to let anyone grab it. Since this is internet superserver I
really expect it to be as aggressive as possible to let the programmed
serviced running if possible. Retry the ports often.
It seems this may be a reason for me to drop xinetd since it is
not acceptable to have this service dying. (Obviously.)

no answer for a long time, unreproducible.
