I have an apex Batch Job which gets stuck in Processing status when run on more than 20 records, say 50, but runs well if run on 20 or less records.
If the same code is run via the execute anonymous window all the records are updated successfully.
There is no error in debug logs initially but eventually an Internal Salesforce Error can be seen in logs although the Batch Job stays in Processing status.

15:31:29.539 (2539559703)|FATAL_ERROR|Internal Salesforce.com Error

Can someone please help me with what is causing this Salesforce Error?

Salesforce support suggested using transient keyword, but even that didn't work. Keeping the variables as transient is also not solving the problem. I've now removed most of the functionality, have also removed Database.Batchable. I'm clearing the main list after every update.
But still the batch job is getting stuck in Processing. This is very weird as a batch of 50 records cannot exhaust all the resources causing the entire operation to get stuck.

Thanks,
Shantanu
