From time to time, I find a command "gzip -f -" running, when I access WHM, process Manager.

Is it a suspect proccess?

Trace shows something like this:

This question appears to be off-topic because it is about basic unix/linux competence which is not sysadmin-specific –  Jenny D Jul 19 '13 at 8:00

gzip is a compression tool, and that data looks like HTTP server logs.

You likely have something like logrotate in place that's automatically compressing your logs.
