Sudheer Vinukonda commented on TS-2883:
---------------------------------------
Adding some error checking and debug logs.We have had other changes (like
turning off session reuse plugin for different reasons) on the hosts, so, not
sure, if the fix really resolves this core. Nevertheless, since, I saw these
error messages appear at the time of the core dump, would be good to have these
included.
