connect() failed (113: No route to host)

[gogobu]

Hi,

I've seen lots of errors like "connect() failed (113: No route to host) while connecting to upstream" in the nginx error log. The upstream server is a Tomcat sitting behind nginx. I've checked the tomcat status and it seems to be running OK with only about 1/3 of the max allowed threads are being used. Any idea what could be the cause here?

Thanks!
Michael
