Hello, Can anyone please explain when exactly these errors occur? 1. ExtConn timed out while connecting. 2. Failure detected: Connection Failure, 110:Connection timed out 3. PingConn timed out while connecting. 4. External processor is not available! 5. Fail all outstanding requests! We're trying to debug the fact that google webmaster tools is reporting an increase in 503 errors since we installed LSLB in front of an already existing webserver. LSLB is reporting those errors regularly in the logs but I'm not sure why that is. At first I thought of a network issue but it turns out not to be the case. I had a ping running from the LSLB box to the webserver box and had 0% packet loss while LSLB reported errors. Maybe someone can explain to me when the above errors happen so we can, hopefully, identify the problem. I'm thinking that maybe LSLB thinks the webserver is dead at some point (maybe because of a slow loading page, timing out?) and the "fail all outstanding requests" error might cause google to receive 503 errors too? I'm not sure what the errors mean exactly and when they happen. Hopefully someone here can help us out.
