Hello good afternoon, If someone can help me I have a problem I have raised Server C4 L2 OFF
It raises the server without any type of error, but when passing the hours, the L2SERVER is closed. Check Memory Disk and cpu and Network and everything is perfect,

anyway u got (7?) crashed threads it seems, can't see very well, post your server specs.

big IO means your server uses to much resources on the disk/database try to stop logging and use SSD at higher read/writes, it also maybe your VPS/Dedicated has started to have faulty drive make backups in any case
