So thanks for that because other people helped and replied . Now this post in general how can I overcome GC problem ? What are the things that I should concentrate on it ?

Tell us exactly what the problem is, what you tried to solve it, what you googled to resolve it before asking us. This is how forums work.

Now i want to submit another one but RAM is not enough , How can i overcome this problem ? Can i fix it instead of increasing size of RAM ? >>>> > >>>> > >>>> > -- >>>> > Regards, >>>> > Navin >>> >>> >>> -- >>> Regards, >>> Navin >>
