xdbc_listener process terminated unexpectedly

[Will Slaughter]

I'm using the FileMaker JDBC driver to drive the data layer of a web application, and I'm noticing a periodic crash in the xdbc_listener process on the server. It doesn't seem to correlate to volume or load, and I can't seem to identify any other pattern in its occurrence.

I'm seeing this message in the stderr log in the FileMaker Server Logs directory:

fmxdbc_listener(259,0x7000061f0000) malloc: *** error for object 0x7fb036825a00: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

Using FileMaker 16.0.4
