Did you call KSPDestroy()? References to two of the vectors are retained by the KSP object, only when the KSP object is destroyed are those references released and hence those two vectors destroyed.<br>
<br></blockquote><div>I did. log_summary shows ksp is destroyed. But I called KSPDestroy() after VecDestroy(). That might cause the problem. Thanks. <br></div><div>Shiyuan </div><br></div>
