I have been watching my uploads and downloads on my XP box very carefully and I notice a strange behavior.
It seems e-mule will drop all active uploading/downloading connections fairly regularly. If I am watching uploads, all the uploads will go to 0 bps at the same time and disappear. If I watch downloads, the downloads go to 0 bps and then disappear. If I look at the statistics window I will see what looks like an upside down spike in the upload rates, and a drop to zero in downloads. Most pending downloads on the queue remain on the queue. The uploads resume as quickly as they stopped, but it takes a good 10-30 minutes before I start seeing downloads again.
At first I thought the problem was my DSL modem was cycling. I did some experiments and I found indeed recycling my DSL appeared almost the same as these sudden connection drops. The main difference is the outage lasts abit longer when I cycle the modem.
I decided to find out definitively if these connection losses were due to loss of network connectivity, so I established a few ssh connections to different remote hosts and issued the commad:
while [ 1 -eq 1 ] ; do sleep 10;date; done
None of the ssh connections have dropped since I started this test, but I the emule connection loss.
Obviously, this test is not conclusive, since it could be something is happening to UDP packets that causes this effect.
Is there any other tests I can run to help isolate this problem?
