Hi All

I am using v9.0044-33 with UTM 120 rev 5. I am also using disk as part of the htp_local_db

It seems that the box is spiking on cpu and the memory is high .I have attached the relevant pic

As part of the troubleshooting I used perf top

what is that process and why it's inroducing spikes to the box?

Code:

/root # top -b -n 1 | head -n 12  | tail -n 5

Memory is normal at the moment:

Most of the swap is allocated to the HTTP proxy (Run top then press 'O' (capital letter o) followed by 'p' then 'enter'. Now processes should be sorted by their swap usage.)

There are too many child-processes for httpproxy is this normal?
