> {code}
> Here is drill's behavior after that:
> 1. Tried to run: "select * from sys.options" in the same sqlline session - hangs.
> 2. Was able to start sqlline and connect to drillbit:
>         - If you try running anything on this connection: it hangs.
>         - Issue ^C --> you will get result if you are lucky (these queries will appear as: "CANCELLATION_REQUESTED" on WebUI)
>           (I only tried querying sys.memory, sys.options which possibly have a different code path than queries from actual user data)
>         - If you are not lucky, you will get this error below:
> {code}
>         0: jdbc:drill:schema=dfs> show files;
>         java.lang.RuntimeException: java.sql.SQLException: Unexpected RuntimeException: java.lang.IllegalArgumentException: Buffer has negative reference count.

> {code}
> I'm attaching results of a jstack  and drillbit.log and so far I was not able to reproduce this problem again (working on it).
