Varnish won't start on reboot

  • 772

I have varnish 4.1.2 installed, it starts fine from the command line but won't start when rebooting the server.

The syslog shows that the address is already in use (port 8080). There's nothing else installed on this server, it's a dedicated varnish server.

When starting from boot it looks like a panic occurs, here's the output from the panic.show in varnishadm

"Assert error in child_sigsegv_handler(), mgt/mgt_child.c line 282:

The VCL file compiles file when using varnishd -C -f /etc/varnish/default.vcl

It looks like the master process is still running. Killing all the varnishd, varnishlog, and varnishncsa processes allows the service to start again.
