RE: cfenvd dumping core

[Luke Youngblood]

Have you used two or more different compiled binaries on the same box
without deleting DB files in between runs?

Initially, I was using the 2.1.13 version of Cfengine from SunFreeware.  I
decided to switch to Blastwave's version of 2.1.14, which is compiled
against a different version of BerkeleyDB.

What I found was that Cfagent and Cfenvd were throwing lots of errors
related to database issues.  Cfenvd would core dump every time I started it.

In order to resolve these issues, I removed all of the databases that
Cfagent and Cfenvd were complaining about (run cfagent -v), then let cfagent
recreate them on its next run.  I didn't have any problems after that.

Just to be sure and cleanup properly, you might first kill cfenvd and
cfservd, then nuke everything under /var/cfengine, and perform a run of
cfagent again.  This should reinitialize all the databases and everything
should work fine from then on.

It seems that different versions of BerkeleyDB create files that are
slightly different in format.

Hope this helps,

Luke

I have almost the same situation.  Although I get a decent core 
almost all the time.  I have both binaries I've compiled (with the 
same versions of tools as you, but only sol8) and ones from 
someone on the list.  Either way, running remotely always 
cores out cfexec or cfagent.

Gentlefolk,
        I'm having a problem where cfenvd is Seg faulting and sometimes
taking cfexecd with it though I don't get a core from cfexecd. It
doesn't
happen with any consistency or pattern. Some machines will have it
happen
every other day others it will happen once a week. I have 134 machines
and I
can go 16 hours without a failure and then have 5 fail in the next 4
hours.

This is with 2.1.14 on Solaris 8 and 9 boxes compiled with gcc 3.3.2
and
linked with OpenSSL 0.9.7. The same version of OpenSSL is on all
machines.
