Thanks for that little bit of info... I didn't realize Nagios behaved this way. I played around with timing out host checks quickly, and even turning them off globally to see if this made any difference, but I still end up in situations where nagios just stops reading the command fifo. I think I may have narrowed it down to the even broker and ndo2db. I'm running the ndo module and logging service info to a mysql database for integration with other internal applications. Nagios seems to be getting hung up talking to ndomod when the mysql database gets somewhat large (>3 Gigs) . If I disable the ndo2db module or just truncate the tables everything seems fine. I've been fine tuning the event broker and the ndo2db config to try to keep the database as small as I can, but I think the root cause of my problem is nagios getting busy dumping event broker data and not getting around to reading that fifo.
