<DD>A function to be called if the database environment panics.
<p>
Errors can occur in the Berkeley DB library where the only solution
is to shut down the application and run recovery (for example, if
Berkeley DB is unable to allocate heap memory). In such cases, the
Berkeley DB methods will throw a <A HREF="../../../com/sleepycat/db/RunRecoveryException.html" title="class in com.sleepycat.db"><CODE>RunRecoveryException</CODE></A>.
<p>
It is often easier to simply exit the application when such errors occur rather than gracefully return up the stack. The panic
callback function is a function called when <A HREF="../../../com/sleepycat/db/RunRecoveryException.html" title="class in com.sleepycat.db"><CODE>RunRecoveryException</CODE></A> is about to be thrown from a from a
Berkeley DB method.
