When severely overloaded there is probably still situations where things may spiral out due to too large queues building up. Especially if your Squid is compiled with way too many filedescriptors. > Another question is: once the system is pushed to a maximum (or beyond), > are things just slow or should abnormal behavior be expected? Unless there is some serious error, slowness. Exception: If you use helpers of some kind and these helpers get too starved of CPU time compared to then Squid may abort when the request queue to the helper grows too large. Regards Henrik
