Autoloader 2022 GDI memory leak

[hans_martin_haga]

While using Autoloader to analyze and upload AutoCAD-files to Vault, the Autoloader would continuously crash after a few thousand files were scanned. It simply closed itself with no error messages. I enabled the extended logging of Autoloader, and found this in the error log

After some Googling, I found that Autoloader seems to have a memory leak. It is exhausting the GDI resources of Windows, and finally crash as the GDI handles/objects go above 10.000. This is a limit in Windows. In the screenshot below, the GDI handles of Autoloader.exe is continually increasing and when it  exceeds 10.000, Autoloader is terminated.

By increasing the limit in registry to maximum (0xffff/65535), the scan completes!

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Windows\GDIProcessHandleQuota

Autodesk Vault Professional 2022 with 2022.3.2 update.

Any input?

You might want to try using AutoCAD's Check-in Folder options instead of Autoloader.

The files are AutoCAD 2000 / R15 and up. Converting them to a newer format is not an option, consuming too much time. Although autoloader has a lot of issues, it is the preferred tool as it gives a nice report on errors that need to be resolved by the customer prior to migration to Vault  - complete as an excel spreadsheet.

After working around the GDI issues, all the files are now successfully uploaded to Vault. It would be nice if the GDI error could be corrected.
