All, I have a few systems that are using xinetd for various things. One is an IMAP mail server, another is a Nagios server that is accepting check results from other Nagios servers (distributed Nagios servers). I have had the following messages in my messages file:
Jun 16 09:05:03 mail xinetd[2108]: Deactivating service imap due to excessive incoming connections. Restarting in 30 seconds. Jun 16 09:05:33 mail xinetd[2108]: Activating service imap Jun 16 09:41:11 mail xinetd[2108]: Deactivating service imap due to excessive incoming connections. Restarting in 30 seconds. Jun 16 09:41:41 mail xinetd[2108]: Activating service imap I have adjusted the number of connections in xinetd.conf and solved the problem. What I want to know id the practical limit on the numnber of connections for xinetd. The default in the system (RHEL3) was 60 instances, with 25 connections per second. But, that seems low. I am tryibg to guage the scalability of the systems while using xinetd. I will investigate using the daemon to listen directly without xinetd. But in the meantime, what is the practical limit and factors that affect that limit, for xinetd ? Your thoughts ?
