To all, Every so often, almost daily, I get this message in logs and squid reloads. FATAL: xcalloc: Unable to allocate 1 blocks of 4108 bytes! Squid Cache (Version 2.5.STABLE10): Terminated abnormally. CPU Usage: 167.029 seconds = 122.739 user + 44.290 sys Maximum Resident Size: 526264 KB Page faults with physical i/o: 0 I have checked almost all references to this problem and some of them are pointing to not enough memory on the server, which is not my case as I have plenty of that. What puzzles me is the amount of memory being allocated to a squid process by FreeBSD. I am running several other caches without any such problems, however, this one is the biggest cache. Could this problem be related to the FreeBSD 5.4 operating system not allocating enough memory for squid? And how could I adjust the OS to eliminate this happening?
