We have 2 servers in replication mode.
The Slave server all of a sudden is not getting updated with the data from Master. That is when one issues the command Show Slave Status on slave server all one sees is:
Seconds_Behind_Master: NULL

I am MySQL developer but not the MySQL Admin.
Our Admin is gone away for a long end of the year holidays, so I am at my wits end to get this URGENT problem fixed.

Your help in this matter is greatly appreciated.
