How do I read the output of `dmesg` to determine how much memory a process is using when oom-killer is invoked?
20,493
The output you provided is missing the information which contains how much memory each process was using at the time the OOM killer was invoked.
Stealing from this question over on stackoverflow, a full OOM killer message will look like this:
[11686.040460] flasherav invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0, oom_score_adj=0

Down at the bottom, starting at the line with printk time 11686.043253, is the table which contains the required information.
If you do not have this table in your output, its possible your dmesg command is defaulting to a minimum output level higher than what this information is logged at.
Try the following command instead:
dmesg -l info,notice,warn,err,crit,alert,emerg
When I dig through the kernel source, I see the process table is logged at the info level. The dmesg command above says to show everything from info to emerg.
Now that we have the information we need, the table is rather self explanatory. The rss column will more or less give you how much memory each process was using at the time. The unit of the value is in pages, which is usually 4kb. So a 2 means 8kb. The oom_score_adj column will tell you how likely the kernel is to kill that process (higher number means more likely).

I asked this question:
Running `sudo /sbin/service mysqld start` causes system to crash
In the comments of one of the answers, a very helpful individual is asking for more information regarding how much memory processes were using when
oom-killeris invoked.The output of
dmesgis ~9000 lines, and hundreds of thousands of characters, though.An example of the output that I see multiple times throughout the output is this:

In the process list that gets dumped into dmesg at the time of the OOM condition, one of the columns should include how much memory each process is using. ...put that output in your question...

Nathan Lutterman over 10 yearsHmmm. Unfortunately, it doesn't look like there is a
-loption in my version of dmesg. Do I need to update this? (I'm hosed, aren't I?) -
phemmer over 10 yearsLooks like redhat
dmesgdoesn't have-l. So withdmesgyou're stuck yes. However if you have your syslog daemon set to pick up kernel messages, your syslog logs might have it. -
Nathan Lutterman over 10 yearsI just took a look through the syslog in "messages", and it looks like it does not have any of those tables of processes. Now I'm sad. I think the last thing I have left is either making
sshdandmysqldexempt fromoom-killer, or disablingoom-killer, which I'm not sure I want to. -
Nathan Lutterman over 10 yearsI can't edit my previous comment so I'll add this: I didn't enable swap before because I did not realize that this was a Xen Virtual Machine. Once I enabled swap, I could actually get MySQL running without everything dying, essentially fixing my issue. For some reason, it's using 363mB of memory, so now I need to figure out how to get the person in charge of the VM to increase the RAM available to it, or decrease the amount of memory that MySQL uses. Thank you Patrick, for all of your help.

Ned about 10 yearsI believe that the memory usage in the task dump is given as number of pages rather than kb.
