title: Error calling Python module function in MySQL Workbench
body: <p>I'm kind of at my wits end here, and so far have had no feedback from the MySQL Workbench bug reporting site, so I thought I'd throw this question/problem out to more sites.</p>
  
  <p>I'm attempting to migrate from a MSSQL server on a Windows Server 2003 machine to MySQL server running on a Centos 6.5 VM. I can connect to the source and target databases, select a schemata, and runs through a pass through once for retrieving tables.  After this the process fails and throws the following errors:</p>
  
  <pre>
  Traceback (most recent call last):
    File "/usr/lib64/mysql-workbench/modules/db_mssql_grt.py", line 409, in reverseEngineer
      reverseEngineerProcedures(connection, schema)
    File "/usr/lib64/mysql-workbench/modules/db_mssql_grt.py", line 1016, in reverseEngineerProcedures
      for idx, (proc_count, proc_name, proc_definition) in enumerate(cursor):
  MemoryError

      self.state.sourceCatalog = self._rev_eng_module.reverseEngineer(self.connection, self.selectedCatalogName, self.selectedSchemataNames, self.state.applicationData)
  SystemError: MemoryError(""): error calling Python module function DbMssqlRE.reverseEngineer
  ERROR: Reverse engineer selected schemata: MemoryError(""): error calling Python module function DbMssqlRE.reverseEngineer
  Failed
  </pre>
  
  <p>I thought this was initally a memory error, so I've upped the memory on the box to 16 GiB.  This error also occurs on any size DBs, as I've tried very minimal sized ones with hardly any tables.  </p>
  
  <p>Any thoughts?  Thanks for looking</p>
