Comment 15 for bug 137514

I should note that a while ago I started using « sshfs -o 'reconnect' » for my mounts. I'm not sure if this hides the bug, or if it's gone.

Using this I don't see the same pattern as before. I don't get freezes or obvious error messages anymore. However, accesses to the SSHFS-mounted partitions do seem to break periodically. For instance, copying files to-and-from sometimes stops working mid-operation, but work upon re-trying. (I acquired the reflex to copy/delete instead of moving things this way.)

I usually have music playing in Amarok all the time, sourced on the sshfs-mounted folders. Amarok used to freeze or do other bad things when the sshfs mounts went bad. Now it only stops playing a song mid-track, and skips to the next one. If I try to replay the skipped song, it always works correctly.

I guess whatever the bug is, the reconnect option hides most of its effects.

In response to Geoffrey's comment, I also tried to do some debugging a while ago. Various options (not only debug, but also things like readahead, sync, cache, direct_io, and something related to threading that I can't find right now) seemed to have effects on the breakage, but due to the rare and intermittent nature of the failures I wasn't able to isolate their effects.

Perhaps with a sure-fire example case like Geoffrey's program somebody can figure out what's wrong.
