[Gluster-devel] Problems with ioc again

I am once more having a problem with the ioc translator. Specifically,
I upgraded the RAM in my gluster client from 4GB to 12GB. Under the
4GB configuration, I had cache-size set to 2048MB. That was working
alright. Once I upgraded the server to 12GB, I changed cache-size to
4GB. After doing that, glusterfs proceeded to use every last drop of
RAM, and all swap, on the system. Not right away of course, only after
I read about, well, 12GB of data.
This behavior was repeated across all 33 of my gluster clients. Even
back when it was set to 2GB, there were times when it would ignore
that setting, and if you look through the mailing list, you'll find at
least 2 people that had the same problem, and didn't get much support.
The ioc translator is an extremely essential part to the operation of
my department. I really need this fixed ASAP- if there is anyone I can
pay to do this, please contact me off-list, as it needs to be done ASAP.
