[MH <mh...@va...>]

What is using the CPU cycles? Is it definitely MH?

Are you looking in the TaskManager/Processes?

Hi All,

Thanks for the help so far. Answers to questions are

1) What happens when you only run the dcam server? Works fine, no memory or
cpu hogging. stays constant.

2) Running windows 2000 pro, 1.5GHz, 256MB ram (was 128MB)

3) Tried running standard MH, ie ini and code_dir. Did not make any
difference.

4) Memory usage always stays the same for all apps
    MH_Proxy = 23MB
    MH          = 45MB
    DCAM      = 12MB

It is always the main MH that starts to gradually use up cpu power, but only
if started after DCAM.

If I start MH_Proxy then MH and THEN DCAM in this order the CPU usage stays
between 4 & 20% and the MH loops per second is around 22.

If MH_Proxy and MH are running then the loops/sec is 10..11. If I now start
DCAM it jumps to 22. Everything still works fine, but only if I specifically
start DCAM last???
