<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">See bug report: under certain circumstances res_odbc can be made to crash.
Adding a shared lock around usage of the con odbc handle is a way to fix this. When a reconnect is attempted, an exclusive lock is held. Result: no usage attempts while reconnecting.
This is hacked up quickly, so could use a bit of review; it wouldn't surprise me if I double-lock something somewhere. (And the assertion I added fails too.) Also, this could be the wrong way to approach this altogether.
@tilghman: is there a reason why ->up is set to 0 after query failure? (See same question in bug report at Cause (1).)</pre>
