How does one delete all the processes still running for a user that is deleted? We have been having some mail issues with an email account for bounce addresses, been receiving millions of emails, and there are loads of server processes. Here is what we have tried:
- Stopping postfix/dovecot didn't stop each individual process
- skill -u username did not work
- deleting the user did not work, the processes are still running using the users old user id which no longer exists on the system
- killall for the process name does not work (e.g. killall dovecot)
here is a small selection of all the processes I cant kill, there's loads of these. new ones keep starting so no good targeting the process ID itself.
