RE: Version 2.2.7 of cfengine released

Hi Mark & Bernard,

I had a similar issue when I upgraded to 2.2.7 however in my case this was due to:
(a) The RPM packager definitions leaked file descriptors:
Initially (leaks descriptors for some reason):
RPMInstallCommand = ( "/usr/bin/yum -y install %s" )
RPMRemoveCommand = ( "/usr/bin/yum -t -y remove %s" )

Final (doesn't leak):
RPMInstallCommand = ( "/usr/bin/yum -d 0 -e 0 -y install %s 2<&-" )
RPMRemoveCommand = ( "/usr/bin/yum -d 0 -e 0 -y remove %s 2<&-" )

(b) Shellcommands and process restarts:
I followed the advice of 
http://www.cfwiki.org/cfwiki/index.php/Hung_Shell_Command

and this resolved my issues.

In my case, all of my file descriptors were due to the Yum command.

I'm using RHEL 5.2 on AMD64

Thanks, 

Best regards,

Brett

Dear Mark and everybody on the list,

I have upgraded our v2.2.6 systems to v2.2.7 but still got the MAXFD errors. Would anyone help?

I found these in /var/log/messages.

and found the defunct children in ps -efww.

The system being deployed is Linux i686.
