Hi all,For the application I am working on right now, I need to send large files between two servers via Apache. I am using reverse proxying to accomplish this. When I hammer my host with requests from the client (several requests in short succession), error.log starts to fill up with "OS Error 10055" messages.
OS error 10055 = No buffer space available.You need to increase your TCP receive buffers, because apache cannot properly buffer the data between the client and the backend, and has to tell the client it cannot serve the request (which is a 503).
Is there a significant bandwidth difference between the connections ?
I notice this problem on httpd 2.2.17; I do not see it on httpd 2.0.64. Other than the standard conversion of some module names (ex, mod_access) for compatibility with 2.0.64, my httpd.conf did not change.
However, the behaviour of settings may have changed.We're going to need a lot more detailed information, such as: MPM used , MPM settings, maxclients, maxrequestsperchild, keepalive and timeout settings, proxypass options set, etc.
