There is a race condition that could cause the load to skyrocket this
way if the main thread god suspended for more than 3 seconds. A
preleminary fix is available at

I haven't tried it with SNMP, but I frequently run a test squid with a
large number of threads on Linux (100 threads).. No problem with the
load here after fixing the race condition.

What kind of objects did you test with? This can happen if your test
data has a average object size less than 7KB and more than 15000 cached
objects. (It shouldn't be a fatal error, but it is).
I assume you haven't changed store_avg_object_size. The default 13 KB is
a safe bet in most situations.
