I'm creating the timers, I've checked to ensure that the brackets are placed properly.
It's mostly the one minute timer that stops working 100%.
It's a global SetTimer (created on OnGameModeInit)
I use foreach and I also Kill the timers OnGameModeExit.

Are there any other factors to continue, I don't do any saving per minute on the timer to MYSQL or anything like that.

It includes the timer for /ajail etc.

show your timer code

Show us your code, and also if you want accurate timers use things such as

Well I would say one of your killtimers thru code is malfunctioning, as any of them can kill another one (like when you KillTimer(Jail[playerid]) but jail has a wrong integer stored in it, so it ends up killing your CheckHealth timer)
Print the 1 minute global timer one's ID, I'm pretty sure it's 1 and somehow you end up killing it
A way to check it would be hooking killtimer to debug it, like printing the timer it's killing.
