So I have problem again!
After 2 days of good working, replication hangs up again!
And I do not make any changes to settings last days. It corrupts by its own.

For now table ibf__uag_gvars is not updating while replicating.
(while relay logs are changing and seconds_before_master==0)


I make UPDATE to another table
UPDATE `jedif1`.`ibf__uag_banlist` SET `member_id`='111' WHERE `id`='1';
and it UPDATES on the slave too!.

and after this query, new queries on ibf__uag_gvars start to work! O_o
(but previous changes was not taken)

how I know when this SLAVE hungs up again?.. How to prevent it?..

> EXPLAIN EXTENDED SELECT * FROM `ibf__uag_gvars` WHERE `name`='defaultShipSpeed';

id select_type table type possible_keys key key_len ref rows filtered Extra
1 SIMPLE ibf__uag_gvars const PRIMARY PRIMARY 66 const 1 100.00

Level Code Message
Note 1003 select 'defaultShipSpeed' AS `name`,'0.21155' AS `value`,'0' AS `private` from `jedif1`.`ibf__uag_gvars` where 1
