Comment 1 for bug 179041

I had same bug.

It is fixed in sshfs 1.9 .
When I was testing with sshfs 1.9, copying dir with 15.000 files in subdirs, and find . it, it was fine for hours.
As soon as I switched back to stock sshfs 1.7, after 3 minutes the copy failed, and I got:

rafal@desktop:~/mnt/ice$ ls
ls: .: Transport endpoint is not connected

rafal@desktop:~/mnt/ice$ dmesg | tail

[61366.198884] sshfs[26006]: segfault at 000000000000791b rip 00002b18121cf6ab rsp 0000000044807cd0 error 4
