Yes, when an essential ICAP service is unavailable, Squid will try
icap_service_failure_limit times and then will declare the service as
down, displaying the corresponding error to users.

FWIW, the error should also "go away" after icap_service_revival_delay
(provided the ICAP server is running again by that time).

You can increase icap_service_failure_limit or mark the ICAP service as
optional (i.e., use "bypass=on").
