mysql error 1206 - recommendation question (2 replies)

Hi,

Under 2.8.3 when trying to delete from the command line a site via:

DELETE FROM piwik_log_link_visit_action WHERE idsite = 2;

I got the error:

ERROR 1206 (HY000) at line 18: The total number of locks exceeds the lock table size

From looking at the doc at (look for the 1206 error section):

http://dev.mysql.com/doc/refman/5.1/en/innodb-error-codes.html

my question is what be the recommendation for what to increase innodb_buffer_pool_size to from the default?
I did try to do smaller data samples via:

DELETE FROM piwik_log_link_visit_action WHERE server_time < DATE_SUB(NOW(),INTERVAL 5 MONTH) and idsite = 2;

but to no avail, got the same error message. When I changed it to 6 months, it came back saying nothing to do, as I
expected since there is not data that old.

Thanks,
Douglas
