Graphite keeps crashing OOM
-
So every few hours Graphite crash, even when it has 2GB of memory, if I look at the log, this is what comes up : https://paste.armada.digital/todawelexi.sql
it seems there is Python Twisted error that keeps repeating over and over again, my log file is 500+MB with a loop of the error in the link above.
-
@rmdes can you ensure that you run the latest Cloudron version 6.2.7 ? There were fixes for graphite in the last one.
-
@nebulon I've had it happen on the latest v6.2.7 as well. Something keeps spiking its memory usage.
-
Updating to 6.2.7 should definitely make the twisted errors sorted out. There was an error in graphite web configuration in previous releases.
-
@girish Happened twice today with 6.2.7.
memory limit at 640MB down from 1250MB, where it had the same behavior. -
@robi OOM twice more yesterday.
It would be great if the message & email sent included the limit reached & time stamp.
The email includes the email time though.

It still runs out of memory with 2.5GB limit.
Also my browser tab for the logs starts timing out as if it can't keep up.. maybe it's in a continuous crash loop.
-
@robi same here, continued crash loop, log file is really huge
-
@nebulon running the latest cloudron version, confirmed
-
I don't have any visible python twisted package error anymore, but it seems the two last OOM event output this error : https://paste.armada.digital/enijufixep.coffeescript
-
I'm also on 6.2.7 but graphite has just started crashing with OOM in the last couple of days (it's never crashed for me before then).
Also agree with @robi that the notifications within Cloudron really ought to include the time it happened (which I can only tell by seeing what time the email notification arrived).
-
A manual restart by pushing the button in services, seems to have calmed down the crashing for now.
I hope the log rotator does it's job, we don't need to have so many huge logs around.
-
Just had another Graphite OOM crash.
Seems strange seeing it's mostly just me using my Cloudron atm and I'm not really doing anything on it.
What does Graphite actually do?
-
@jdaviescoates that service (graphite+collectd) collects the data used in the graphs, like memory usage over time. Given that it causes issues from time to time and also we don't really utilize it well, we are thinking of maybe collecting the data on our own and ditch graphite.
-
Thanks
@nebulon said in Graphite keeps crashing OOM:
collecting the data on our own
What would that look like?
-
@jdaviescoates we don't know yet
-
@nebulon Caprover uses Netdata... would that be possible?
-
After a server restart, graphite won't start. Reconfig doesn't help. -
I decided to reboot the box for security upgrades (from notifications) and it came up without errors this time.
-
Graphite OOM, again.
