since you don't mention what system you are running I may be wrong but I
used to have this problem on our SNI RM400 proxy server with the OS SINIX
5.42 (which is, more or less, a SVR4 system). It turned out that the login
defaults for users were ~32 MB virtual memory per process. As soon as our
squid cache grew to about that size, it would crash with the error message
you describe. After setting this to unlimited in RunCache, the problem went
away.

As a matter of fact I've tweaked 4 user oriented limits in RunCache:
  ulimit -c 0 # 0-size core (important as our squid cache grows to up to
                                 # 200 MB)
  ulimit -d unlimited
  ulimit -s unlimited
  ulimit -v unlimited

I hope this helps in your case as well.
