Exporter crashes frequently with "fatal error: concurrent map writes" when running multiple databases

[msafdal]

I'm currently running the exporter (currently v2.0.3 but the issue was present in at least v2.0.2 as well) with 4 databases configured. The exporter crashes frequently, many times per day, with the following error message "fatal error: concurrent map writes".

Running as a standalone exporter has never presented similar errors so it seams to me that it's related to having multiple databases in the same instance.

Attaching stacktrace. Please let me know if any more information is required.

I was just about to open a ticket for the same issue -
I have this happening here with two databases configured.

This is in the environment and with the version discussed in
V2.0.3 - GLIBC Version not found #323
.

Thanks for reporting, we will look into this. I think this is possibly related to the issue's we've seen between godror and odpi-c under load.

Can you share your config file, omitting any sensitive data?

ah, I think I get it. We're caching metrics on the metric level, since we're multi-database we need to cache metrics on the database level.
