Meandre server memory leak : CoordinatorJobBackend #73

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
It doesn't seem like SEASR folks are going to fix the memory leak in 1.4.7,
we would have to do this ourselves.

This I think is fixed -needs to be confirmed. JDBC Driver for mysql has a bug 
you
need to close the Statement and PreparedStatements -closing result statement 
does not
completely free the prepared statement memory
