The forking method Squid currently uses causes the child process to get as much virtual memory allocated as the Squid worker process was using at the time, including a full copy of the cache_mem contents. In a low memory system its better to start a bunch of the helpers via startup=N before the parent allocates too much memory and keep them running than it is to start later via idle=N when traffic is going through. Now that you know your peak usage is around 60 helpers worth of traffic you may want to check out what the memory profile is like with startup=50.
