Description

I have 4 lighttpds which serve as proxy to tomcat5 (and do some other things - generally ~250 requests per second). Very rarely, a few times a day I get following errors on each of them:

It happens only when light is trying to forward request to tomcat (and 99.99% of communication is OK).

I'll second the problem. I am using lighttpd as frontend server for a reverse squid. The goal is to distribute the requests between several servers. In the setup lighttpd distributes the request to a single squid server.
