I think you'd have better luck posting this to the nagios-devel list, so I'm cross-posting it there now. Provided you're subscribed there, we should be able to drop this from the nagios-users list where it really doesn't belong. Anyways... What command is being sent into the command-pipe when nagios crashes? Have you made any modifications to the code? Does this happen with latest CVS code (without any local modifications)? -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 ------------------------------------------------------------------------- Take Surveys.
