Crash DB core problem

[Undertaker 0]

Hi,
I have problems with the fact that sometimes the core of the database crashes. I don't know where the problem may be, I tried everything here, the source doesn't report any errors to me during compilation. The core of the database usually crashes with a many warps. However, there is only 1 person on the server at that moment. The VPS has 4GB of RAM, so the problem of insufficient memory is ruled out here. Here I attach the syserr database and channel1.

DB syserr:

SYSERR: Feb  1 20:32:29 :: pid_init: 
Start of pid: 14640

SYSERR: Feb  1 20:51:12 :: ChildLoop: AsyncSQL: query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 (query: REPLACE INTO affect  (dwPID, bType, bApplyOn, lApplyValue, dwFlag, lDuration, lSPCost) VALUES(1, 515, 12, -99000, 0, 402482, 0) errno: 1064)
 

 

Channel1 syserr:
