Question

I have a slave that was started after the master had been running. I started it at a position in the master bin log that was when I started to import databases on the master. This slave has been running, but now is stuck and not progressing.
It has been stuck at relay master log 000055 and position for hours.
Results of show slave status:

I look up what is at that position in the master binlog and its just a drop temp table:

DROP TEMPORARY TABLE IF EXISTS `rmtemptableinclude` /* generated by server */

Whenever I see replication hungup on something, there’s an error displayed in the STATUS output…

You can try skipping one statement in the replication:

STOP SLAVE;
SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
START SLAVE;
