When sketch bigger than +/-14000 bytes sketch get hang-up.
That is for duemilanove 328 and for the uno too.
Now I must make the sketch much smaller, i.e. half or max. size of 28000 bytes!
-14000 bytes?
+/-, not exactly...
Not exactly what?
Post your code.
The total length of the strings and initialized data in your sketch has probably exceeded the amount of free SRAM. You could try to move some of the strings and/or data to PROGMEM.
