Dear all,
I've been trying to track down a problem with timeouts when pulling data from an rsync daemon and I have now run out of any useful ideas. The problem manifests itself when I try to transfer a large directory tree on a slow client machine. What happens then is that the client rsync process successfully receives the list of files from the server, then begins checking the local directory tree, taking its sweet time. Since I know that the process is quite slow, I invoke rsync with a timeout of 5 hours to avoid dropping the connection. Howerver, after a little over 1 hour (usually 66 minutes or so), the server process simply gives up. I have verified the problem under rsync versions 2.3.2, and 2.4.6 and up (including 2.5.5), testing a few different combinations of client/server versions (althoug the client is always a linux box and the server always a solaris box). It looks to me as if something kicks the server out of the select() call at line 202 of io.c (read_timeout) despite the timeout being correctly set to 18000 seconds. Can anybody think of what the problem may be? See all the details below.
