<div class="textblock"><p>This represents a consumer sequence mismatch between the server and client views.</p>
<p>This can help applications find out if messages have been missed. Without this and during a disconnect, it would be possible that a subscription is not aware that it missed messages from the server. When acknowledgment mode is other than <a class="el" href="group__types_group.html#gga8fcb50e6e7312834791f9e237d28e873afd91fe31cf57c68863ca3090b07c296c" title="Requires no acks for delivered messages.">js_AckNone</a>, messages would ultimately be redelivered, but for <a class="el" href="group__types_group.html#gga8fcb50e6e7312834791f9e237d28e873afd91fe31cf57c68863ca3090b07c296c" title="Requires no acks for delivered messages.">js_AckNone</a>, they would not. But even with an acknowledgment mode this may help finding sooner that something went wrong and let the application decide if it wants to recreate the subscription starting at a given sequence.</p>
<p>The gap of missing messages could be calculated as <code>ConsumerServer-ConsumerClient</code>.</p>
