'Transport endpoint is not connected' every couple of days

[GoogleCodeExporter]

I am running several Drupal servers on Apache that use an S3 bucket as their 
shared back-end. Every couple of days, one of the servers will lose their 
connection to the S3 bucket with the resulting 'Transport endpoint is not 
connected'' message when trying to ls the mounted bucket. My current solution 
is:

sudo apachectl stop
sudo umount /var/www/html/files
sudo s3fs mybucket -o use_cache=/tmp -o allow_other,uid=48,gid=48 /var/www/files
sudo apachectl start

I haven't found anything in a log that points me in the right direction as to 
why the bucket is losing it's connection. Any help is appreciated - I'm just 
not sure where to start troubleshooting this.

Thanks in advance!

Hi,

There is latest s3fs version 1.77  on 
Github(https://github.com/s3fs-fuse/s3fs-fuse).
Please try to use it, and if you have the problem yet, please run s3fs with 
"-d"(if possible with "-f") and check log file.

Thanks in advance for your help.

I've updated my servers to v1.77. Unfortunately the issue still persists. Is 
there a log I can start with or a debug mode I can enable?

Hi,

Please use latest version.

For debgging, you can run s3fs with "-f -d" option, which means running 
foregrund and putting debug message on console.
If you get a error, maybe something information is put on console.

And If you can, please try to run s3fs with "multireq_max" option.
So the s3fs send requests as parallel, this option is count for parallel and 20 
as default.
If you can, please set multireq_max is small number(ex, 3-5 --> 
"multireq_max=5").
I hope it decreases this error.

Thanks in advance for your help.
