Anyone came across similar problem before

Hello Pankaj

It seems like you have passed the limit of available memory in the target system.
You may to go back one step in your version control system, to the previous working version, compile it and have a look in the Build messages how much memory the application is calculated to consume. Looks something like this (SC050-120):

   Danfoss PLUS+1 GUIDE Software: [MEMCalc] Version: 7.2.10
   ***

   ****** Memory Usage in bytes ******
   Type            Total           System          Application     Free            Used/Avail     
   ------------------------------------------------------------------------------------------------
   ROM             507904          93926           2448            411530          1%             
   RAM             129536          34400           0               95136           0%             
   NV              4000            0               0               4000            0%             


There you can see an estimate of how much free memory you have (about 411 kB in this example). The % shows how much is used in percentage. Please note that the memory calculation is just an estimate.
ROM is basically where your application is stored.
RAM is for temporary values. Arrays often have a big impact here.

If the ROM is full, the application code most often can be optimized to consume less memory. This basically means using less components in the design. Look through your code and see if there, for example, are portions of code that is often repeated and that can be placed in a loop instead, or in a page like a subfuncion etc. There can be many ways and most applications can often be optimized a little bit more...

The "Development Guideline" document (found in you Danfoss folder on the Start menu) is also giving a few examples.
