RE: cfenvd dumping core

[PAUL WILLIAMSON]

I just tried to delete all my db files on one of the clients...

I ran cfagent -v on the client (I did not delete the db on the 
policy master) and it left a big core dump.  

$ file core
core:           ELF 32-bit MSB core file SPARC Version 1, from
'cfexecd'

So, it looks like cfexecd is core dumping.  Interestingly, my 
cfagent file is configured to restart cfenvd, cfservd and cfexecd
if necessary:

        "cfenvd" restart "/usr/local/sbin/cfenvd"
        "cfservd" restart "/usr/local/sbin/cfservd"
        "cfexecd$" restart "/usr/local/sbin/cfexecd"

If I remove cfexecd$, I get no core dump.  Is this the correct format 
for starting up cfexecd?

This is a possible explanation for the problem. One might also try
downloading the latest snapshot from www.cfengine.org where a few
patches are applied.

Certainly I cannot understand why cfenvd should cause cfexecd to
crash.
They are utterly independent. The only conceivable link between them
is
Berkeley DB.
