Reserved FDs and CPU spikes

Squid Object Cache: Version 2.2.STABLE5-hno.20000202

Running under FreeBSD 4.0, I'm seeing the CPU useage
of squid go from 10-20% up to 95%+ and at the same
time the number of reserved file descriptors jumps
to consume all available file descriptors, and squid
starts warning that I'm running out of FDs. Is this
a known problem? I increased the FD limit to 2048
from 1064 and recompiled, only to find the problem
show up again a few minutes later.

File descriptor usage for squid:
        Maximum number of file descriptors: 2048
        Largest file desc currently in use: 354
        Number of file desc currently in use: 322
        Files queued for open: 0
        Available number of file descriptors: 1726
        Reserved number of file descriptors: 1727
        Store Disk files open: 1
