Process 'usim_x86' running for months, using 600+% CPU

Hi all,

I notice on these two particular HA Pair of VSX Firewalls, there is a process running 'usim_x86'

It is using 600+% of CPU and seems to have been running for a long time, I believe the entire uptime. (it seemed to be more initially, which is impossible, but apparently something with the multithreading can make the CPU time grow faster than real time)

Uptime:

10:34:11 up 63 days, 23:21, 1 user, load average: 13.42, 12.35, 12.69

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
27135 admin 20 0 0.130t 2.308g 667156 S 618.3 1.8 485113:15 usim_x86

1308 admin 0 -20 9366456 3.788g 884176 S 1.7 3.0 1314:19 fwk3_dev_0

It seems to be something to do with Threat Prevention features I think? But checking my other firewalls which are the exact same model and version I do not see this process.

Do you guys have any idea if this is normal? It does not seem ideal to me to be running a process continuously for that long if its using that much CPU.

Thanks

Reviewing top output on gateways running UPPAK is ineffective, you will need to review cpview and HCP outputs to understand further if there is a problem.

Please refer: sk180299: Linux commands report a high CPU load average when SecureXL operates in the User Space (UPPAK) mode

Thank you, I checked with cpview as per the SK and it shows here very low CPU usage. Good to know that we shouldn't rely on 'top'
