I found the problem. The issue was the following:  My batch process had a global variable  which was keeping instances of lists of records that were created in each execution of the method "execute". Therefore I was unnecessarily accumulating records in memory and that caused the error "Batchable instance is too big" . 
 
I suggest you to check the status of the global variables after each execution and you may find the solution to your problem as well.

I am also getting this error on my batch.  I had no problems for the past 3 months with my batch until today.

Have you figured out what was causing this? We have also started seeing this with one of our batch.

 

Any information on the issue would be greatly appreciated!

Not yet... In my case is really odd because I'm not querying data from database, i'm getting the data from an external api using callouts. I'm imagining that the error is trigger because some var instance, maybe a collection, that has to many elements, but I'm not sure...  If I get the cause of this issue, i'll post it here.

 

Good luck.
