Swap file numbers! Help!

I keep seeing this in my cache.log:

97/12/21 18:23:43| You've run out of swap file numbers. Freeing 1MB
97/12/21 18:24:15| You've run out of swap file numbers. Freeing 1MB

It's squid 1.1.19 on linux 2.0.30, 2.75 GB of cache. I upgraded from squid
1.1.18 two days ago and now I'm seeing this message. Squid has been
restarting all day as a result of this message.

Just before restarting Squid says this:

97/12/21 18:12:52| Finished rebuilding storage from disk image.
