Michael,

Just a guess based on:  " By “killed” I mean the container generates an error 
message indicating “killed” and the entire docker container process 
disappears "

        Maybe you are seeing a message like this? (not for mysqld, but for 
some docker process? Or the process in the container?)
                "kernel: Killed process 9163, UID 27, (mysqld) 
total-vm:2457368kB, anon-rss:816780kB, file-rss:4kB"


        It sounds like the OS is forcing the process( whole container?) down 
due to memory constraints/other resources. ( REF: "OOM Killer" )
        Can you get the full error message? ( If my guess is correct you can 
find it in the OS that is hosting the container(s). )
                /var/log/messages   ???

                # or go fishing...
                grep oom /var/log/*
                grep total_vm /var/log/*


My general guess is that you need to give the hosting OS more ram.
        Given that PSPNG, Loader, UI, (WS?), DB are all sharing that same RAM 
pool.... you might need to just not run some of that at the same time on your 
laptop. :^/


I have found that my loader can eat 4G of RAM for "large group jobs" ( 100k+ 
). (I was actually seeing it die with "Heap size" errors until I expanded the 
ram for the process.) However, it may also be true that the RAM growth is due 
to not one job, but several "large" jobs running at the same time too.

HTH.

Subject: [grouper-users] PSPNG and tier packaging

Good morning all,

Lately, I have been doing a lot of testing using the TIER Grouper package.  
Part of the package includes a 389 directory server (great choice!) and I 
have configured the environment to publish groups to 389 using PSPNG.  I have 
getting more and more intense with the work as time goes on to be able to 
effectively demo Grouper on my laptop.  Over time, the “daemon” container is 
killed.  I haven’t been able to figure out what is going on or why.  I 
decided to remove the “provision_to” attributes from the folder hierarchy I 
was putting into 389 and noticed the daemon container wasn’t being killed any 
longer.  The daemon container essentially runs gsh -loader and that is all.  
Turning PSPNG back on again, and the daemon container gets killed again.  By 
“killed” I mean the container generates an error message indicating “killed” 
and the entire docker container process disappears - the gsh -loader is no 
longer running.

I hope this helps point in the direction of a problem.  I would really like 
to be able to reliably run PSPNG.  I am including my PSPNG config below.  
When PSPNG is running, it works great with this config.  If anyone is 
curious, givenName is being used because eduPerson is not yet part of the 389 
config within the TIER Grouper package.
