[Linux-HA] Re: Load balancing fails

[Ralf Bardoel]

Dear "all",

I managed to get rid of the interval warnings, but still the website is 
unreachable after some time. The logfiles make no record at the incident 
and the web servers are all monitored and show no downtime. When port 80 
is "down" I can still ping the ip of the cluster. Has anyone some advice 
on how to increase the loglevel and how to discover the problem? Regards,

Ralf
