SQLSTATE[HY000]: General error: 5 Out of memory (Needed 4194092 bytes)

I'm receiving the following error on my shared hosting box:

SQLSTATE[HY000]: General error: 5 Out of memory (Needed 4194092 bytes)

This error is only triggered on a specific page.

I guess this indicates that I am reaching the upper limit of the 64MB allocated to me in my current MySQL environment.

Does this mean that a single query is going over (returning) 64MB of data? If so, i guess i can just track down and tune that specific query? Or isnt that t开发者_如何学运维he correct approach?

Appears it failed to allocate about 4 MB of data during the query. You may be able to see this in the log output, such as with slow_queries. It's most likely a SELECT query, you may be able to find it by doing this in a near parent directory:

grep "SELECT" `find | grep "php$"`
