Comment:

 Hi,

 This looks like your Varnish is suffering under too much IO load, and
 page-ins take longer than the CLI timeout causing the manager process to
 SIGQUIT the child.

 Remedies include:
 - Reducing disk IO (more RAM / smaller cache set)
 - Increasing cli_timeout parameter
 - Putting the Varnish SHM file on tmpfs, to avoid it being paged out. See
 https://www.varnish-software.com/static/book/Tuning.html and google for
 more information.

 Regards,
 Martin Blix Grydeland
