Geetanjali,
There is a difference between next-key locking, gap locking and locking
reads.
Next-key locking and gap-locking are used with normal Selects statement in
Innodb, whereas locking reads wont release a lock on the whole column until
transaction completed, and not just selected values.
Could you please answer these questions also. What does data_free field
from SHOW TABLE STATUS shows?
When should we run optimize table for innodb tables?
I read various blogs. They said data_free shows free space inside the
innodb tables. But after doing *optimize table*, the value inside

Without seeing actual values I can only give an educated
guess:

Replication novice
I have a master server at the office and a replication server at
home. This setup has been working for a couple of years.
Occasionally the replication server gets out of sync (usually
following a internet problem and the vpn going down.)
I just stop the slave, make sure
Whilst there are a few possibilities, check on the master that your binary
logs are being written to. Another possible reason could be filtering.

Hello guys, some points to check here:
1-) Is the master server configured with sync_binlog=1 ?
2-) About the SHOW SLAVE STATUS output, when slave seems to be just reading
events from master, is the Exec_Master_Log_Pos incrementing or not?
3-) Why are you reconfiguring all the replication just
You can paste the show slave status\G here for us to review and on Master,
show global variables like 'log-bin%'; show master status ( 3 to 4 times
continuously )
