I've just got a call from my staff, they can't move appointments in the calendar or create new tasks. After the server was powered out mistakenly for a few minutes, they are getting an exception thrown at them every time they try to move an appointment stating OD found a duplicate primary key. I was able to reproduce the problem (see error message below). From what I can gather when looking at the various tables with Navicat, it seems that signalod is the table causing the problem. Its current autoincrement value is 1482965 and last record in it shows 1482964 (first one is above 88000)

Question: what's the best course of action to solve this? I am leaning towards performing an ALTER TABLE signalod AUTO_INCREMENT = 1482966; but I don't want to break anything else in the process.

We are using OD 14.3.35.

Thanks in advance for your help!

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

OK, problem solved. The database maintenance tool has repaired it. We never have problems with OD, that's why it took me so long to think about using it...

What I would try first is REPAIR TABLE signalod. That often works for me when I get the duplicate primary key error. It would be a good idea to backup your database before running this command.

Looks like you figured it out, but if you're curious why this happens its because mysql was in the middle of inserting a row into the table when the power cut out, so the row got inserted but the auto-increment didn't get incremented. Its fairly common when power is interrupted during use, and DBM should take care of it in the future. And if you can't run DBM for some reason, then what Chris posted is the next step. But as he mentioned always backup before you run a repair command because if you have some larger data corruption than just autoincrement it can cause you to lose data from the table, and OD support techs are also always available to help with these issues if you call in.
