Hello,
Squid reload can cause to swap=0.
This problem can be generate by reloading (squid -k reconfigure) squid.
After every reload it increases the memory used by squid process, if we continue its causes the swap to 0 and squid crashes.
I am Using default squid configuration.
./squid -v
Squid Cache: Version 3.1.9-20101129

Squid Version 3.1.10 also shows same behavior.
valgrind (run for 3.1.10) shows as below:
