What does the 'rtcli async executor process' process do on a Cisco ASA and why would it cause high CPU load?

I noticed that the CPU on our ASA had jumped from around %4 to 30% consistently a few weeks back.  The process below seems to be causing the load, but I can't find any information on what it does and how to resolve the issue.

ASA# sh proc cpu-usage sorted non-zero
PC         Thread       5Sec     1Min     5Min   Process
0x08a24505   0x1bdb0124    25.4%    25.6%    25.6%   rtcli async executor process
0x081ecc51   0x1bdc0f3c     4.7%     4.3%     4.1%   Dispatch Unit
0x08e4687c   0x1bdc0528     0.3%     0.3%     0.3%   ssm4ge_cfg_poll_thread
0x08a496d0   0x1bdbecf8     0.1%     0.1%     0.1%   Unicorn Admin Handler
0x0866d56e   0x1bdafd1c     0.1%     0.1%     0.1%   ARP Thread

A little more background that has me concerned is that I have the exact time when the jump occurred.  Since that time, I've lost ssh access to the ASA and can only access it via Telnet internally or the ASDM.  I checked the certificates and a new one was generated exactly when the spike occurred.  I am unsure wether or not that was a system triggered certificate generation, or if I have a security issue I need to address.  Heartbleed maybe??  

Any insight would be greatly appreciated.
