Hi Razvan

Thanks for your quick and accurate reply.  I have made the changes which seems to have dropped my errors down from several thousand to just a handful, which is fantastic!

It looks like the fix has worked nicely for the usrloc module but the dialog module does not appear to work in the same way...

I'm not quite sure what the memory warning means though as I have forced the module to have 215MB of fixed memory (66MB currently used as idle) and has a 512MB swap file.

Although these changes have fixed the error messages the process now does not restart properly... where as before it had several thousand errors, but still worked.
