I am maintaining 2 identical ( I believe, i have inherited the installation) QNX 4.25 servers. Both are running the same tasks.
Site A runs the tasks without issue but site B runs the CPU to 100% and stalls. On investigating this, I noted that Site A shows a CPU speed of about 333 where site B shows about 266.
Friom Site B:

I have had the hardware checked and both are running Intel PIII 850Mhz processors. On boot, the BIOS shows the chip at 850Mhz also.
My background is in Linux and I do not have a great deal of experience using QNX. Are there any better tools available in QNX 4.25 for investigating the true CPU speed or understand how to locate the cause of the systems high utilisation?
