[mythtv-users] Theme memory usage

[Craig Treleaven]

Hi:

My main backend/frontend is an older Mac Mini with 2 GB of RAM. 
After I upgraded to 0.25, I noticed that sometimes recordings would 
fail, ala:

TFW(<filename>) Maximum buffer size exceeded.  file will be 
truncated, no further writing will be done ...

The system was using about 500 MB of swap and OS X is abysmally slow 
when dealing with swap. 

I switched from the Blue Abstract theme to MythCenter-wide about 3 
days ago.  I haven't had a failed recording since.  Swap usage has 
grown to over 100 MB since then.  I ran this system for years on 0.21 
with MythCenter-wide and virtually never had a failed recording or 
laggy performance.

So I wondered what other people's experiences are:
-Is Blue Abstract a particularly memory-hungry theme?  Is it possible 
it is buggy and is leaking/wasting memory?
-Or are all the modern, graphical themes THAT memory hungry?  Is 4 
gigs necessary?  More?
-Is there another modern theme that works better on a 
memory-constrained system?
-I recall there was talk about tweaking the parameters for the 
Threaded File Writer.  Is that something I should look into?

Appreciate any input.
