Particularly since the error is segmentation violation. I'm not a programmer [more like a jack-of-all-trades SA on more machines than I'd care to remember] but a segv error says the program is trying to access memory outside certain limits. Maybe its some sort of buffer over-run. > Do things just 'go wrong' in programs like vdeliver mail and > what's my best course of action, update vpopmail?

But I'm more suspicious of the program if that's the only time it happens. If it were hardware problems then when the system was loaded down other things should fail, and your load isn't that of a heavily loaded system. Bad ram, that only gets used when something uses a lot of memory could be that, but if you are using ECC or parity memory [any one using machines in production SHOULD but many dont] you would see errors in the logs. I run parity in the older machines and ECC in the newer ones. But we are quite small at the moment. -- Bill Vermillion - bv @ wjv . com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
