Hi All,
We had a power outage and after that I am getting DB error #1812. 
I am also getting DB error #1062, but only received the 1062 once.
Here is the email I received from the alert for #1812:
[SELECT count(*) FROM ost_syslog log WHERE 1]
Tablespace is missing for table osticket1
.ost_syslog
.<br /> <br />

Here is the error for DB error #1062

The same ticket last created keeps duplicating itself and no tickets are coming in after that. It's only the same ticket getting recreated over and over.
