Hi @vclaudic
thanks for the extensive bug report! Do you see the same stack traces when running under mod_wsgi
and with runserver
? If it's only with mod_wsgi
, you could try and add
WSGIApplicationGroup %{GLOBAL}
to your mod_wsgi
configuration. From the mod_wsgi docs:
When this is used with the %{GLOBAL} value, it forces the WSGI application to run in the main Python interpreter context of each process. This is preferred in this scenario as some third party packages for Python which include C extensions will not run in the Python sub interpreter contexts which mod_wsgi would use by default. By using the main Python interpreter context you eliminate the possibility of such third party packages for Python causing problems.
Hi Benjamin,
Thank you for your answer. Here are my answer in regard:
-> When running with runserver, here is what’s happen when trying to log in the admin GUI:

I hope this match to your exactions and may help you… hum… to help me ! ;-)
Thank you very much for your help and feedback and have a good day.
All the best,

Thanks @vclaudic, this helps a lot. I think I'm starting to see what is happening here. Looking at the stack traces, it seems like there is an infinite recursion going on (notice how the frames start to repeat after a while). Normally, Python should raise a RecursionError
at some point, but apparently doesn't always do that, depending on circumstances I haven't quite understood yet (see e.g. https://bugs.python.org/issue37402), and instead crashes.
Now, the next question is, why is there a recursion error. Based on the stack frames, it looks like we're collecting local variables for a database span, and one of the local variables is a queryset. To show a representation of the queryset, we call repr()
on it, which causes a database query, which we again capture in a span, which collects local variables, one of which is a queryset.... and we're in an infinite recursion loop. This is bad, and we need to fix it.
But first, a possible quick workaround. Collection of local variables can be configured using the collect_local_variables
setting. By default, we shouldn't collect local variables for transactions/spans. Did you maybe change that setting to transactions
or all
? If yes, I suggest trying it with errors
. Otherwise, try to disable it completely by setting it to off
.
Now, to actually fix the issue, we need to special-case QuerySets in our transform
function, similarly how we already special-case some other types.
Hi Benjamin,
Clap ! clap ! I'm really impressed !
I've tested your workaround and I may say that from both points of view, i.e. Apache and runserver, it works fine ! I've changed my setting according your advice and replace "all" with "errors" and yet the admin login doesn't crash both Apache and runserver.
I really thank you verrrrrrrrrry much for your support, feedback and reactivity ! ;-)
Have a good day.
All the best,
Vincent
@vclaudic that's great news, thanks for reporting back! We already have an issue to improve upon the transform
function (https://github.com/elastic/apm-agent-python/issues/182), so I'll go ahead and close this one :)
Hi,
First of all, please receive my best wishes for these new Year and decade for you and your relatives ! :-)
Yet, let's talk about my mistake. I've started, few weeks ago, a new Django project based on Django 2.2.9, Python 3.7.6, PostgreSQL 12.1, Apache 2.4.41, mod_wsgi 4.7 and the Django modules elasticsearch 7.1, elasticsearch-dsl 7.1 and elastic_apm 5.3.3.
With "'elasticapm.contrib.django'" declared in installed-apps, as long as DEBUG is set to True, I've no mistake, i.e. every thing works fine, but as soon as I'm setting it to False, both Apache or the runserver are sadly crashing.

Regarding the mod_wsgi apache module, here is how it's called in Apache configuration: ——— … WSGIDaemonProcess calliope.ecqualis.lan processes=2 threads=15 display-name=%{GROUP} … ———
I've the same mistake when increasing the processes to 8 and threads to 25.
Here is the way Apache was built: ——— …

As I've deployed an internal ELK instance (7.5.1 versions) for that project, I'll be pleased to also use it with APM.
So for any additional information allowing you to provide some help, please just drop me a line.
I thank you in advance for the time you'll spent on this and wish you a good day.
All the best,
Vincent
