Since its only ~300% I'm more inclined to think it's a weird issue with the squid memory cache objects. The bug of this week seems to be a few people now seeing multiple-100% memory usage in Squid on FreeBSD 7+ 64-bit OS. Due to Squid memory-cache objects being very slightly larger than the malloc page size. Causing 2x pages per node instead of just one. And our use of fork() allocating N time the virtual-memory which mallinfo might report. Asim Ahmed: does that match your OS? Amos
