Do you have any detailed steps for how to upgrade to 0.9.9 to 0.9.13?

Rather than trying to upgrade immediately, I'd recommend installing the latest
separately, so you can try to reproduce this issue without disturbing your
actively-used deployment. You can then upgrade when ready, keeping this
investigation independent of that.
When ready, you will need to:
# Read the release notes of the releases which have occurred since 0.9.9, so
you know what has changed and whether it might affect your upgrade. In
particular, you'll want to take note of deprecation/compatibility notes. Each
release since 0.9.9 which deprecates something or introduces incompatible
changes has such a section.
# Take high-level note of how your current Guacamole configuration is set up
with respect to which extensions are installed, etc.
# Essentially start over, following the installation instructions for
0.9.13-incubating (as documented in the manual) and your notes regarding how
your old Guacamole server was set up. If your 0.9.9 deployment is in
production, you should do this on a separate server so you can safely switch
back if necessary.
# If you are using a MySQL or PostgreSQL database, apply the upgrade scripts
for the versions after 0.9.9, to apply any schema changes. Be sure to back up
your database before doing this.
Avoid the temptation to just copy everything over and replace old with new.
Upgrading from 0.9.9 to 0.9.13, you'll want to be as conscious as possible of
the new installation. Many things have changed, and some old configuration
mechanisms were deprecated and eventually removed.
Finally, if you run into problems, the mailing list would be the place to go
for assistance: http://guacamole.incubator.apache.org/support/#mailing-lists

> Hi,
> I have a running guacamole server on version 0.9.9. the problem is that the
> guacd is causing a very incremental high load. I tried to upgrade the machine
> to 8 cores and 8 GB of ram, however the issue is still persists. once I
> restart the service everything back to normal, but it will keep rising again
> after short amount of time. I have checked the running porcesses and the main
> Guacd process is sleeping .. not sure if that the default behavior of the
> service or not.
> Any help will be appreciated.
> Thanks alot in advance
