Why are my downloads stopping all the time?

Problem

Transmission may pause your downloads unexpectedly sometimes. This article explains some common triggers for that behaviour.

Triggers

• Your filesystem may be full. Check if you have enough free space left on your filesystem.
• Your filesystem may be corrupt. Use a filesystem utility like fsck or Disk Utility to check your filesystem for errors
• Your harddrive may be defective.

Defective Filesystem

If your filesystem is defective, transmission may write the the following message to its logs:

generic i/o errno from errno: Operation now in progress

At the same time there should be some new entries in your syslog that look a bit like this:

Aug 19 03:26:27 kernel: attempt to access beyond end of device
