MySQL 5.7 is evil

Hello,

  days ago I switched from MySQL5.6 to MySQL5.7, fresh DB, InnoDB,  
dspam with TOE.

DSPAM stops to work for a tons of "lock wait timeout". Back to MySQL  
5.6 and DSPAM returns to work greatly. No differences on hardware and  
resources. Only the DBMS engine changed.

I think that MySQL5.7 introduces something that DSPAM doesn't like.  
Does anyone experience this problem?

Thank you
Best Regards
Marco
