Seeing the following in nginx.log
The remote ZWC connection is being made through a firewall (within a LAN) and all appears to be working okay. I believe this message appeared when I was uploaded a couple of small images into a new email.
2010/05/26 10:43:19 [warn] 707#0: *55360 a client request body is buffered to a temporary file /opt/zimbra/data/tmp/nginx/client/0000000019, client: 172.29.28.3, server: zimbra01.pacifera.com, request: "POST /service/soap/SendMsgRequest HTTP/1.1", host: "zimbra.domain.com", referrer: "http://zimbra.domain.com/zimbra/"
I also see in the same log file
With that one I am guessing it is just the Ajax NoOpRequest not closing quick enough; or not closing at all ?
