This temporary fix removes the memory leaks present in the DAB class library for connect/disconnect and commit/rollback. Unzip leakfix.zip in your ibmcpp directory. It replaces the following files: dll\cppods3i.dll lib\cppods3i.lib lib\cppods3.lib bnd\daxscl.bnd You must first bind this version of the class library to the database: sqlbind ibmcpp\bnd\daxscl.bnd Then relink your applications to use the new library.
