-----------------------------------------
I have a similar issue with Spark 2.3.2.
Here is a stack trace:

It happens during ETL process that has about 200 steps. It looks like it
depends on the input data because we have exceptions only on the production
environment (on test and dev machines same process with different data is
running without problems). Unfortunately there is no way to use production data
on other environment, so we cannot find differences.
Changing compression codec to Snappy gives:
