uid 90, gid 90:

Jul 28 12:11:47 n02asp7 heartbeat: [8756]: info: Starting child client 
"/usr/lib64/heartbeat/ccm" (90,90)
Jul 28 12:11:47 n02asp7 heartbeat: [8768]: info: Starting 
"/usr/lib64/heartbeat/ccm" as uid 90  gid 90 (pid 8768)

# ls -la /var/run/heartbeat/ccm
insgesamt 8
drwxr-x--- 2 root      root     4096 18. Jul 17:30 .
drwxr-xr-x 5 root      root     4096 28. Jul 12:13 ..
srwxrwxrwx 1 hacluster haclient    0 12. Jul 14:04 ccm

And indeed:
# chown hacluster:haclient /var/run/heartbeat/ccm/

fixes thes problem.

Let me guess, it's because ccm now drops root privileges?
