What is "supervise log" process?

[Fli]

Hi, i want to ask what is supervise and why these processes use quite high hard disk operations (I/O)?

at the beginning there is a TID value, so i did:

lsof -p 715088

result:

so it appears supervise is a qmail (http://www.lifewithqmail.org/lwq.html) thing


If you run qmail or qmail-smtpd under supervise

supervise, which monitors a service and restarts it if it dies.

If you're logging to a supervised log service
