That would be right if they were negatives or enough to wrap 32-bit back
to positive.
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?
