Stalwart Container stops responding

[w4tzmann]

Hello,
A few weeks ago, I installed Stalwart (using built in RocksDB) via Docker Compose on a Debian13 vServer (2 CPU, 4GB RAM). Unfortunately, Stalwart keeps crashing. I can't find any errors in the trace log (but it stops writing as soon as it crashes). In the container, the Stalwart web server does not respond via stalwart-cli or curl.

The Docker host does not have high utilization. There is nothing helpful in the Docker log either. The container itself is still shown as up.
Any ideas on how we can find out why Stalwart keeps crashing?

Hi, try checking the Stalwart logs for details, you might need to set the log level to trace. Also, RocksDB does not work well with some hard drives, you might want to try using PostgreSQL if that is the case.

Hi,
Thanks for the response.
Stallwart has been running for 5 days now. I couldn't find anything in the trace logs before that. If I have the problem again, I will upload the sanitized logs.
