Zabbix mysql blocked by bin_log errors

Zabbix never fails to find new and unusual ways to break. The most recent breakage occured because the housekeeper is running "unsafe" sql. You'll find this repeated a thousand times in the mysql-error.logs:

130617 17:30:35 [Note] The following warning was suppressed 50 times during the last 38 seconds in the error log
130617 17:30:35 [Warning] Unsafe statement written to the binary log using statement format since BINLOG_FORMAT = STATEMENT. The statement is unsafe because it uses a LIMIT clause. This is unsafe because the set of rows included cannot be predicted. Statement: delete from history_uint where itemid=2506343 limit 500

I just decided to disable the housekeeper. It slows performance of the database down anyway. In /etc/zabbix/zabbix_server.conf uncomment the following line:


And then restart Zabbix. You should be good to go. You can also vote on my bug report here.
