I'm suspecting that dots and brackets are not allowed in column names of an Esri Geodatabase, see https://support.esri.com/en-us/knowledge-base/faq-what-characters-should-not-be-used-in-arcgis-for-fi-000005588

You can e.g. use an AttributeManager to rename the attribute names yourself before passing them on to the Writer.

Yea, it's exactly that :)

Hi @david_r​ 

Thanks for the update - but it worked fine in 2022.2.5, without any warning - it only appeared, when we migrated to 2023.1. Similar other warning appeared in 2023.1 for GeoDatabase, but not in 2022.2.5

The above actually has written correctly into GeoDatabase

Hello, i got the same problem, When i executing the workbench with server version 2022.2.4 there was no problem. With server version 2023.1 i got the same warnings as the topic starter,. The log file contained at the end 16978 pages with these warnings. (the log file on the 2022.2.4 version was only 1 page and no warnings. anyone any ideas?

here are the last lines, to give an idea:

@david_r​ @hkingsbury​ @federico​ @rudy_v​ 

We're currently aware of a bug that is affecting all Esri formats writers (and PostGIS/PostgreSQL writers when "use lowercase attribute names" is enabled).

The issue results in excessive log warnings related to the renaming of attributes. This includes attributes that are not getting written to the target file/table, such as format attributes (ex. fme_feature_type, fme_data_type). In some cases, FME will log one error message per attribute per row, which not only causes huge bloat in the log file but also can cause performance slowdowns.

We've tagged the issue as critical and will update everyone here once we've released a fix.

The ticket number for this issue is FMEENGINE-81406.

At the moment to workaround the issue you can either disable Log Warnings via FME Options, or you can try using an AttributeExposer + AttributeRemove to remove the attributes before they reach the writer that is logging the warnings.

@danminneyatsaf Do you have any updates on this excessive logging issue? We encountered it on the environment that we upgraded recently.  We disabled the warnings for the specific workspace that is encountering the issue.  I am concerned that we might miss a different issue with the warnings disabled.  We are seeing some logs taking between 20-50 GB of space on the server and it is causing storage alerts on our environment.

@danminneyatsaf @mark2atsafe  I’d also like an update on this issue which is negatively impacting one of our clients.

Hopefully this has been resolved in the latest 2023.x?

Just to update everyone - the issue with excessive logging was resolved under a related ticket (FMEENGINE-80292) and has available in build 23781 and newer!

If you have any questions or problems please don’t hesitate to reach out to our team!

I still have similar warnings in 2024.0 version:

POSTGIS Writer: Renamed user attribute 'kml_schema_data{11}.name' to 'kml_schema_data{11}_name' based on format constraints for invalid characters, length, and case
I guess it is related to the same issue. But another reader type. Is there ticket for this as well?
