[Bug 371776] Re: sshfs mounted device got disconnected.

[Geoffrey]

I have seen this before, and in 9.04 as well.

When running a program that continuously appends lines of text data to a
file over an sshfs mount, sshfs crashes every time.

Ironically, turning on the debug output with the -d switch is the only
thing that makes the problem go away, though it cripples the execution
speed, so this supplies no information.

I am 99% sure that it must be some kind of stack or buffer overflow as:

 trickle -s -u 150 -d 150 sshfs -f Geoffrey at xxxxxxxxxxx: xxxxxxxxxxxx/

executes successfully, albeit with the program executing at a quarter
the speed it should.

(trickle limits the network bandwidth available to the process)

This would indicate a problem with outstanding requests, but, setting -o
max_read=1 and / or -o max_write=1 does not solve this, or make any
discernible difference whatsoever.
