The crontab is ~100 lines long but nothing is related to Nagios (except the stupid script that restart it in this case). are there any cronjobs (even unrelated) that run around this time though? my thought that something like a log rotation or a mysql dump might be stealing all of some kind of resource, causing the forks in nagios to fail. As I told you, the server is constantly loaded by all those cronjobs and daemons, the load average is between 1 and 4. Nagios should not fail in this situation. could you post (or send privately if you prefer) your nagios.cfg?

Nagios should not fail in this situation. this is true, but i'm wondering what makes you situation so different from other people's (my nagios server has had loads like this and not exhibited this behavior). max_concurrent_checks=5 could you see if scaling this down, and/or check_interval for your services in services.cfg has any effect? sean -- signature.asc Description: Digital signature
