FSCLIENT Panic</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Panics with this category are raised on clients requesting services provided

by the file server. Typically, they are caused by passing bad or contradictory

values to class constructors or member functions. </p>

<p>The thread causing the panic is terminated. </p>

<p>To avoid confusion, we need to emphasise that the panic category is the

14 character string <i>FSCLIENT panic</i>, and that the word panic is part

of the panic category. </p>
