multiple notifications sent out after system is recovered from crash

[vesuviustty]

We are using osTicket 1.16.1 and use the autocloser plugin. Whenever our system crashes and boots, if there were any issues that had to be closed during the down time, they will be closed upon system boot. That is acceptable. But we noticed that there are multiple attempts to close the ticket and the corresponding notifications get registered in the ticket view numerous time and also multiple identical email notifications will be sent out all parties, which is irritating. How can we best address this issue? Is this is a bug that that not recognize failed attempts and tries to send a notification per each failed attempt?
