Problems with zabbix 1.8.2

[toxot]

Good evening.

I'm install zabbix 1.8.2

From old version (1.8) i export several templates and config hosts. In attempt to enter to the monitoring-overview and try to see data i see the following error.

error in query [select distinct h.hostid, h.host,i.itemid, i.key_, i.value_type, i.lastvalue, i.units, i.description, t.priority, i.valuemapid, t.value as tr_value, t.triggerid from hosts h, items i left join functions f on f.itemid=i.itemid left join triggers t on t.triggerid=f.triggerid and t.status=0 where (h.hostid in (10089,10088,10087,10063)) and h.status=0 and h.hostid=i.hostid and i.status=0 order by i.description,i.itemid] [incorrect key file for table '/var/tmp/#sql312_10b_3.myi'; try to repair it]
mysql_fetch_assoc() expects parameter 1 to be resource, boolean given[/usr/local/www/zabbix/include/db.inc.php:544]
mysql_free_result() expects parameter 1 to be resource, boolean given[/usr/local/www/zabbix/include/db.inc.php:546]

I can not understand what the reason of this, base didn't broken.
I already try to delete templates that i exported. Then situation has not changed. Moreover, this error shows in several groups. Groups haven't difference ( hosts have identical templates).

I needs help of specialists.

Thanks in advance
