the reset may help your problem but u can as well do a soft reset using *#7780#.
This also appears to be a bug since one of my friends also got the same error. I havent got this yet though
Normally, With 128 MB of RAM, this should not be a problem.
I run multiple applications and dont get this anyways !!!
