Hi,
Please include to output from show system resources, show processes stack, show system internal processes cpu & show system internal kernel [cpuhogmon | memory {usage | global [detail].
Did you just notice this or is this a pre-exisiting condition? Have any changes been made recently?
Thanks

should i open TAC for this ?

Hi
I did a little digging and found a couple actions you can try:
1) Disable features one-by-one (If problem resolves note the feature)
2) Possible workaround is to switchover from active to standby. (Or a reload)
# sh sys internal processes cpuPID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10904 auser 20 0 4340 2352 1560 S 5.7 0.1 1730:13 first-setup.cor <----look for this process
If you see it increase note any changes made that would coincide with the age of the hung process then run the following commands:
# show tech detail
you will want to run this from the VDC showing the hung process and save it to bootflash:
# show tech detail > bootflash:sh_tech_det
Pull the accounting log:
# show accounting log
Then open a TAC case.
Thanks
