This is a Squid bug or misconfiguration. If you are using a UFS-based
cache_dir with multiple workers, then it is a misconfiguration. If you
want to use SMP disk caching, please use rock store instead.

HTH,

Alex.
P.S. This assertion has been reported several times, including for Squid
v4, but it was probably always due to a Squid misconfiguration. We need
to find a good way to explicitly reject such configurations instead of
asserting (while not rejecting similar unsupported configurations that
still "work" from their admins point of view).
