cf-agent receiving SIGINT on one client

[Bob]

I have one client and I keep getting this message:

Received signal 15 (SIGTERM) while doing [lock.handle_users.files.edit_line.comment.-client669._etc_passwd_5524_MD5=d3e66baa4f28c36002bd5ec26282cc5a]
Logical start time Thu Dec 1 06:41:26 2016
This sub-task started really at Thu Dec 1 06:41:39 2016

When I run cf-agent from the command-line as follows:

# time cf-agent -KI -v > /tmp/cf-agent.log

real    0m25.997s
user    0m21.821s
sys     0m1.368s

The process appears to execute quickly. The logs do not appear to contain anything helpful. Clients are supposed to run once from between the top of the hour and 15 minutes passed, then again from 30 minutes past to 45 minutes past (splay time of 10 minutes). Any suggestions?

-K ignores locks so not no the same as a normal run. And the issue might
well be locks.

Can you provide the offending promise?

Try raising the debug verbosity using "-d", and see at the end of the logs. And as Neil mentioned, avoid -K if you want to reproduce the issue.

BTW Bob, if you are reading this, your mailbox sends auto-replies as "not being monitored". You may want to fix this. :-)

I've shutdown cf-execd and am running cf-agent from the command-line. I am having trouble determining which promise is giving me the issue. When I run without debug, cf-agent never terminates:

# time cf-agent -I -v  > /tmp/cf-agent-nodebug.log

I killed it after about 5 minutes.

Next, I ran with some debug. When I do this I get a segmentation fault:

time cf-agent -I -v -d 1 > /tmp/cf-agent-debug.log

The last thing I see in the log file is different:

I think this is a red herring. I suspect the issue is related to adding users to the system. I was able to confirm this by removing the user management bundle from the list of sequences and cf-agent completes in under 13 seconds.

I will keep looking. Thanks for the suggestions.
