Hi, I reproduced the problem, and saw that the c-icap server (or its squidclamav module) reports a 500 internal server error when clamd is down. I guess that's not bypassable? The c-icap server log reports: Mon Jan 29 08:30:35 2018, 5134/1290311424, squidclamav.c(1934) dconnect: Mon Jan 29 08:30:35 2018, 5134/1290311424, entering.
