The parameter maxdsize (=67108864) seems to be responible for the restarts. The
amount of memory which has already been allocated by the squid process grows
until it reaches the value of maxdsize. Nevertheless if I choose 52 MB for
cache_mem (cache_mem_low 90, cache_mem_high 93) squid shows the same behavior.
Though I would expect that squid throw away "in-memory object data" when 46 MB
of memory have been allocated. (The same happens if I choose the default value
(8MB). The size still grows, but less rapidly.) Maybe this is a bug in HP-UX
malloc.
