I've just submitted a similar bug report for varnishlog, with a potential fix. If you're using systemd to control varnishncsa, it's probably the same issue. Try adding a larger -t parameter to the varnishncsa daemon (/etc/systemd/system/varnishncsa.service copied from /lib/systemd/system/varnishncsa.service and then tweaked).
