Spamassassin infinitely eats server disk space (in overlay2) #5

Open dtrckd opened 3 years ago

Hi,

Using docker-postal in a VPS I have encountered a "no space left on device". After having investigated, I figured out that the issue comes from the spamassasin container.

I turns out that there is an infinitely number of empty folders created within postal-spamassasin-app container, inside the /tmp folder, here's an example (I verifierd that the sise in /var/lib/docker/overlay2 growth as well because of those folders) : 

bash-5.0# ls -A  /tmp | head |  xargs du -sh
8.0K    .spamassassin10001DGbDLFtmp
8.0K    .spamassassin10001UD2WI8tmp
8.0K    .spamassassin1000243lK31tmp
8.0K    .spamassassin100026eeizUtmp
8.0K    .spamassassin10002JhfDx4tmp
8.0K    .spamassassin10002s1rxFetmp
8.0K    .spamassassin10002xi6f1Ntmp
8.0K    .spamassassin10004VepMcItmp
8.0K    .spamassassin10005NLVJRhtmp
8.0K    .spamassassin10005TAVulwtmp

After running the container for ~1days, I got more than 70k folder here

bash-5.0# ls -A  /tmp | wc -l
71776

Finally here is a sample of this container logs which may help understanding why all those folder are created

$ docker logs postal-spamassassin-app 2>&1 | tail -n20
config: no rules were found!  Do you need to run 'sa-update'?

[and so on...]
docker logs postal-spamassassin-app 2>&1 | wc -l

Any idea how we can solve this issue ?

I precise that running sa-update inside the postal-spamassassin-app container gives me the following error:

bash-5.0# sa-update
config: no configuration text or files found! do you need to run 'sa-update'?
Timeout::_run: check: no loaded plugin implements 'check_main': cannot scan!
Check that the necessary '.pre' files are in the config directory.
At a minimum, v320.pre loads the Check plugin which is required.
