----------------------------------

Hey Matt- so I think this is deja vu all over again.  I think we've actually talked about this issue, or related, before.  Yesterday, I had a fairly catastrophic hung state on a Maria cluster, which definitely left the DB in a weird spot.  When I did a "odbc show all", the boxes cored.  As you note, this is definitely a libodbc issue.  The boxes that experienced this were all CentOS 6 with an older 2.2.14 version of unixODBC installed from the package manager.

There were a couple of boxes that were running 2.3.1 and 2.3.2, and on those boxes the crash didn't happen.  Seems likely to me that this issue has been resolved.  Not sure if you actually want a work-around, or maybe just some documentation notes that there are known stability issues with unixODBC on older releases.

> This issue seems to be exercised when a database connection is unavailable or unreliable.  It seems to be possible to duplicate this either on cdr_adaptive_odbc or standard realtime.
