Re: Help please

Did you find a solution to this?  I'm seeing a similar problem in
cfexecd.  When cfexecd is run in daemon mode and it wakes up to make its
scheduled run it also gets a SEGV cfpopen().  This means I can't use
cfexecd to keep cfengine running and I have to rely on cron instead.
I'm seeing the same problem on Solaris, Linux and HP-UX.
Here's the result of dbx during such a crash:

cfpopen(/var/cfengine/bin/cfagent -z)
Got cfengine SMTP server as (mail.procket.com)
Got cfengine sysadm variable (address@hidden)
Got full qualified name (modena.procket.com)
