title: DB2 connect SQL1042C error
body: <p>When I give DB2 CONNECT command I get the error saying "SQL1042C  An unexpected system error occurred". The most weird thing is this issue is intermittant.</p>
  
  <pre><code>sqlcode: -1042; 
  sqlstate: 58004; 
  DB2 connect command: connect to dbname user db2admin using password;
  </code></pre>
  
  <p>My DB2 version is: DB2/NT64 9.5.0</p>
