Hi! I'm running CFEngine2 (2.2.10-4build2, Ubuntu Precise).
I have this server which boots from PXE. There's foo to bootstrap it, then a cron-job runs a shell scripted for-loop: | for i in 1 2 3 4 5 | do | /usr/sbin/cfagent -qKvf cfagent.conf >>/var/log/pxeboot.log 2>&1 | sleep 5 | done This is done to speed up configuration of the server. The first iteration of this loop, also the first time cfagent runs on the system, CFEngine runs a Perl script which in turn runs apt-get. The apt-get process is now taking more than five minutes to complete and gets sent a TERM signal which kills it instantly leaving packages in broken state. Five minutes is also when cfexecd fires off its own cfagent process, and i found this second cfagent is sending TERM signals to the subprocesses of the first (looped) cfagent instance. This is documented behaviour, prevents 'runaway' processes, though i could not find the seemingly preconfigured ~300 second runtime limit in the reference. It should be configurable through the ExpireAfter and timeout settings but they seem to be ignored? The relevant cfengine bits read: | control: | any:: | actionsequence = ( shellcommands ) | | shellcommands:: | class1.class2:: | "/etc/foo/installpkg.pl $(AllClasses)" I tried changing the actionsequence to include ExpireAfter: | control: | any:: | actionsequence = ( shellcommands.ExpireAfter30 ) I also tried adding 'timeout=3600 expireafter=3600' to the shellcommand: | shellcommands:: | class1.class2:: | "/etc/foo/installpkg.pl $(AllClasses)" | timeout=3600 expireafter=3600 and i tried setting ExpireAfter in control: | control: | any:: | ExpireAfter = ( 30 ) And combinations of the above. None seem to work. At this moment i switch off cfexecd during the looped cfagent runs but i'd rather not. Any light on why i cant seem to put an end to the brutal killings? :/ With regards, -Sander. -- | 0 bottles of beer on the wall, 0 bottles of beer, you take 1 down, | pass it around, 4294967295 bottles of beer on the wall. | 4096R/20CC6CD2 - 6D40 1A20 B9AA 87D4 84C7 FBD6 F3A9 9442 20CC 6CD2 _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
