[OpenSIPS-Users] presence prepared query errors

[Bogdan-Andrei Iancu]

Hi Juha,

This does mean you encountered a deadlock. By the sounds of it, you're 
likely to be using InnoDB.

So, you should issue "SHOW INNODB STATUS" from the mysql command line.

In that output, look for the "LATEST DETECTED DEADLOCK". There you will 
see 2 transactions, (1) and (2). You can see the exact queries that 
caused it and the table locks that each hold/trying to acquire.

Just post it here to see what are the queries blocking one each other.

Regards,
Bogdan
