Hi,
finally got it working - several problems were fixed:
- directories not available -> create them
- lock wrong permissions -> chown
- pid file not available on startup (too fast) -> sleep 3
For reference here is a diff:

Seems to be stable now.

Hi!
As an exercise you could try to write your own apache RA. That shouldn't bee to difficult. Alternatively you could try to hack the RA until it works. Then report your insights.
Maybe you want to stop your apache and try "ocf-tester (if available) to test the RA (also good when hacking it).
