Unfortunately, stopping squid isn't really an option I can use for debugging here.
An MBUFTRACE kernel might show where the mbufs are used, but there is lots of code that fails to implement it correctly.
kern.mbuf.nmbclusters = 1038371
Here's a netstat -mssv at the time when squid is complaining:
18043 mbufs in use:
3502 mbufs allocated to data
