I need a help with "server crash"

Hello boys. I have a problem with my server, but I don't know what is.
Here is information from crashdetect, I post this here because I don't know
how to reach this.
This is from crashdetect https://pastebin.com/DjtiCFKs - I get this from server.log
Only when player will be 30 or more, server gone crashed. Who will help me, I will
respect him, and somebody who will try to help me.
Here is COMMAND /ipm, how I can see, I think that command ipm is problem, but I don't know..
HINT: I use only command in format: CMD:command(playerid,params[])
Here is command: https://pastebin.com/V9CN58Gs
Translate on SCM texts.
SCM(playerid, INFO Isklucivte primanje na privatni poraki.");
- SCM(playerid, INFO You turn off your private messages, now players can't send you message.");

SCM(playerid, INFO Uklucivte primanje na privatni poraki.");
- SCM(playerid, INFO You turn on your private messages, now players can send you message.");

SendClientMessage(playerid, INFO Privatni poraki na igracot se iskluceni.");
- SendClientMessage(playerid, INFO Player has turned off private mesages.");


SCMF(id, 0xEEE854FF, "((PM od(from) %s[%d]: %s))",GetName(playerid),playerid,tekst);
SCMF(playerid, 0xECCD2DFF, "((PM do(to) %s[%d]: %s))",GetName(id),id,tekst);

And also I transformer any commands from (YCMD:) to (CMD:)
Any help is welcomed. Thanks.
And sorry for my bad English..
