Are you running the Docker image?

Do you have free memory on the host and for the container?

Are you running the Docker image?

It runs inside a lxc container with python3 virtualenv

Do you have free memory on the host and for the container?

# free -m

The logs for the two instances that I'm running don't show any such error.

What is the base OS?

Had this been working fine before? Or did you just start trying the bot?

@tomkap Also, please accurately test and confirm that the container is writable, but preferably is not persistent across restarts. Only the sqlite database directory should ideally be persistent.

Additionally, GPT says:

1. Check and adjust the semaphore limits on your system. On Linux, you can view the current limits with cat /proc/sys/kernel/sem and adjust them using sysctl if necessary. Increasing the limits may resolve the issue.
2. Ensure that the directory used by Python for semaphore files is accessible and writable by the user running the Python process.
3. Stale semaphore files left over from crashed or improperly terminated processes can cause issues. Cleaning up these stale files can sometimes resolve the problem. However, you should be careful and ensure that these files are not currently used by active processes.
   Please let me know how these go.

Freeing some extra memory seems that resolved the issue. The bot is running for 2 days without an issue.
