Yes, our proxy did use swap until I disabled it :-)
2GB RAM, squid process is stable at roughly 1GB process size,
nevertheless the machine started swapping.
I never figured out why, but the proxy is running fine without any
swapspace. This is dangerous with a squid still growing.
Using swap (for the squid process) affects performance.
I would reduce cache_mem and probably the size of the cache_dir(s) to
avoid this situation.
