I'm puzzled by the two statements: "it stops writing the log files for about 30 seconds [and] clients cannot access the cache" and "Squid continues responding [to] all the requests normally". So, are you saying that Squid is processing requests and returning content quite normally, without the users noticing any problem, and it's just that the log files are not being written for 30 seconds or so? Are you saying that all requests get fetched directly from the origin servers, and the cache is not being used, for these 30 seconds? Maybe you could clarify? > This is the last request until it holdups: > 1503416750.346 386 192.168.0.2 TCP_REFRESH_UNMODIFIED/304 235 GET > http://www.mysite.com user HIER_DIRECT/www.mysite.com - This is the next > request: > 1503416781.864 141376 192.168.0.2 TCP_MISS/200 5599 CONNECT > play.google.com:443 user HIER_DIRECT/play.google.com - Okay, so I see there's a 36 second gap between those two requests; were clients sending requests during that time? Have you tried doing a packet capture on the Squid box's interfaces to see whether client requests are coming in, but Squid is not sending the proxied requests out, or whether it's sending the requests, egtting the response, but not sending that back to the client?
