EARM Error code

EARM indicates that ibnotify's asynchronous event notification mechanism failed to rearm itself. This generally occurs when an ibnotify Callback has attempted to rearm itself by returning an illegal value or when a fatal driver error (EDVR) has occurred.

Solutions

Ensure that the value being returned by your Callback function is a valid ibnotify mask value.

Return a zero value from your Callback function to unregister the asynchronous event notification mechanism. Then call ibnotify to re-enable notification.
