> the server is running for weeks, no crash no powerloss Remarkable. In the initial post of this thread you state that squid is crashing periodically. We need to focus on squid here. Not your system. These crashes can lead to this error and , for instance. Swap.state becoming corrupted. Not that the error 6 maybe a logfile beeing to big, or swap.state over 2 Gig, would lead to the same error, and that situation would then become tied to the disk-space-over-limit error. M.
