这个进程是EMC POWERPATH的一个加密进程，出现占用CPU过高的情况，根治的方法是升级版本，但需要重启分区。。。。。
临时解决办法：
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 two lines, save the file.
****NOTE**** Do NOT comment out the lines with #. The last two lines must be removed entirely.  Using # to comment out the lines will 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

AIX emxp_xcr 进程cpu 开销过大导致db 很慢
