Recently we had been bitten by a Systemd limitation at the “Tasks” created per-unit ie., process. This includes both the kernel threads and user-space threads, with each thread counting individually.
Am writing this blog as a reference for someone who might come across this limitation.
We have been actively working on migration DB instances, from one DC to the newly built DC .The instances on the newer DC were provisioned with the latest hardware and latest Debian OS. Below is the detailed spec of the system.
Core : 44Core
HardDisk. : SSD
IOPS : 120K
