Adrotate_tracker causes MySql crash | WordPress.org

Hello,

Recently I get periodic crashes on my website. Upon investigation I saw that during the server crash there are multiple queries that are stacked.

An excerpt (truncated) from the running MySQL processes:

496146 gas_lev_gas localhost wpdb Query 145 executing SELECT timer FROM lev_adrotate_tracker WHERE ipaddress="203288032500" AND stat="i" AND
496148 gas_lev_gas localhost wpdb Query 140 executing SELECTtimerFROMlev_adrotate_trackerWHEREipaddress="2032880327600" ANDstat="i" AND

496164 gas_lev_gas localhost wpdb Query 143 executing SELECT timer FROM lev_adrotate_tracker WHERE ipaddress="203288012500" AND stat="i" AND `

Any intel is much appreciated

Thank you,
