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
