s3fs dies due to segfault during rsync from nfs mount to s3fs

[GoogleCodeExporter]

Detailed description of support request:
Every now and then s3fs causes a segfault.
My use case is that I rsync to sync some NFS mounts to a s3.
rsync works well for a few hours and then I see the following message in rsync:

rsync: recv_generator: failed to stat "<localmount>/<filename>": Software 
caused connection abort (103)
<s3fsmount>/tmp/
rsync: recv_generator: mkdir "<s3fsmount>/tmp" failed: Transport endpoint is 
not connected (107)
*** Skipping any contents from this failed directory ***

Here's a the entry from /var/log/messages from that time rsync failed:
kernel: s3fs[31176]: segfault at ffffffffffffffe8 ip 000000000043235c sp 
00007f30d734b4e0 error 4 in s3fs[400000+51000]

Hi,  ZionS

Thanks a reporting this problem.
(I close this issue, because duplicate issue 400 by you.)

Please wait for solving this problem, ( but maybe this is hard to find a resin.)

Regards,
