This process is an encryption process for EMC PowerPath, with high CPU usage, and a radical approach is to upgrade the version, but need to restart the partition .....
Temporary Solution:
1. Halt the currently running process with kill-9 <pid No. >

2. To prevent the emcp_xcryptd daemon from coming back up on a reboot,before the next reboot.
Edit The file/etc/powerpathextensions which contains these lines:
mpxext:cfgmpx
Gpxext
DMEXT:CFGDM
VLUMDEXT:CFGVLUMD
Xcryptext:cfgxcrypt
Remove The last of the lines, save the file.
****note**** does not comment out of the lines with #.  The last of the lines must be removed entirely. Using # to comment out the lines would cause PowerPath to not configure devices on reboot.

3. Remove the following line From/etc/inittab and save the file:
rcxcrypt:2:wait:/etc/rc.emcp_xcryptd xcrypt_rc >/dev/null 2>&1
