[squid-users] Detected DEAD Parent

[dtom]

Hi

My cache.log often says 'Detected DEAD Parent' and 'TCP connection to X.X.X.X/8080 
failed'.
If my alert tool catches 'Detected DEAD Parent', that tool tells me this event.
But I can access to the internet through squid box.
I want to tweak timing of 'Detected DEAD Parent's logging , because this 'mistaken' 
event 
is not useful for me.
Which directive should I tweak in squid.conf?

Thanks
Tomi
