I have the current configurations active on my default.vcl varnish file on the machine that balances the load for other two machines (the other two machines also have varnish active).
My intention is to have this server do only the load balancing and the other machines do the processing and also their own caching.
My problem is that even with the config testing (not even a stress test or anything, just a few requests a minute) I get the guru meditation error and have to restart varnish.
This is the default.vcl for the load balancing server:
backend vader {
.host = "app1.server.com";
.probe = {
.url = "/";
.interval = 10s;
.timeout = 4s;
.window = 5;
.threshold = 3;
}
}
backend malgus {
.host = "app2.server.com";
.probe = {
.url = "/";
.interval = 10s;
.timeout = 4s;
.window = 5;
.threshold = 3;
}
}
director dooku round-robin {
{
.backend = vader;
}
{
.backend = malgus;
}
}
sub vcl_recv {
if (req.http.host ~ "^balancer.server.com$") {
set req.backend = dooku;
}
}
Am I doing something wrong or missing something?
EDIT:
This is varnishlog's output:
