This Exception suddenly started showing in my logs. I didn't made any changes in my code.

I guess this might be due to a timeout?

I'm seeing a mention of a quartz job in the stacktrace. Looks like something has setup a periodic job and the AOP transaction management has picked up on it.

It looks like your transaction lasts than transaction timeout limit. You should increase transaction timeout limit..

But I am not sure about that, you should post more stack trace to understand the reason of rollback.
