lock problems with big file copy operations?

[Jeff Wasilko]

I'm using cfengine to copy my "/usr/local" (/is/dist/pkg), and I noticed
that some newly added files weren't getting copied.

Running cfagent in debug mode show:

Checking copy from scully:/is/dist/pkg to /is/dist/pkg
Server connection to scully already open on 7
Authentic connection verified
GetLock(copy,_is_dist_pkg__is_dist_pkg,time=1063834465), ExpireAfter=120, IfElap
sed=0
GetLastLock()
CheckOldLock(lock.cfagent_conf.mila.copy._is_dist_pkg__is_dist_pkg)
Lock lock.cfagent_conf.mila.copy._is_dist_pkg__is_dist_pkg last ran at Wed Sep 1

Couldn't obtain lock for lock.cfagent_conf.mila.copy._is_dist_pkg__is_dist_pkg (
already running!)
Closing current connection


cfagent isn't running manually, and trussing cfexecd makes it look like
it's just in a 'idle' loop.

Stopping cfexecd and removing the cfengine_lock_db seems to fix the 
problem.

How can I go about debugging this?

Thanks!
