Hello Harshit ... I'm assuming "MyssqlTcp" is the name of a process
group in your NiFi GUI?? If so, can you show a screenshot of the NiFi
processors that are in that process group so we can see which processor
or where in the processing things might be hanging up?
Given no other info, the easiest, most likely way for something like
that to happen in NiFi that I've seen (learned the hard way) is to have
a mis-configured GetFile processor (eg: have the Keep Source File set to
true, and have the Polling interval set to 0 sec).
Thanks for any further info you can provide.

Hi Harshit,
That does not look typical of NiFi, what it looks like to me is a
cryptominer. Is this NiFi connected to the Internet without
authentication or with a weak password? Publicly accessible NiFi
servers will quickly be exploited to run ExecuteProcess and deploy a
miner.
The fact that the name doesn’t seem to match anything related to NiFi
and that the CPU usage is high indicate this may be a malicious
process. If you kill it there will usually be some sort of persistence
mechanism that will restart it. If you check and confirm it’s an
unwanted process I would strongly advise deleting this NiFi instance
and redeploying.
Kind regards,
Jim
