Is anyone starting to get agmcalls.log and agmmemorystats.log files created in directories that PDFs are exported/stored in?

Since updating Acrobat to 26.002.21996 (installed October 6, 2026), two plain-text files named agmcalls.log and agmmemorystats.log are being created in folders that contain PDFs. If you delete them, they come back the next time the user opens or previews PDFs in that folder.

Environment:
- Windows 11 25H2
- Adobe Acrobat 26.002.21996 (AGM.dll file version 8.0.5.1)
- Acrobat Reader 26.002.21901 is also installed on the same machine; it was not updated
- The PDF preview handler is Adobe's pdfprevhndlr.dll
- The folder is on a mapped network drive; I have not yet confirmed whether local folders are affected too

What the files contain:
- agmcalls.log starts with "AGM Call Counts" and lists call tallies grouped by component (RasterPort, ColorSpace, PaintServer, Function, Image, etc.), followed by CTTAG: lines (CoolType counters)
- agmmemorystats.log starts with "*** AGM shutting down ***" and contains a memory allocation table per object type (AVGlobals, PMGlobals, RasterPort, PathPoints, etc.)
- No file paths, document text, or user data, only counters

This looks like Adobe Graphics Manager (AGM.dll) diagnostic output that is written to the process's current working directory when the rendering engine unloads. Both files share the same timestamp, which matches when the user opened or previewed PDFs in that folder. No environment variables or registry settings on the machine reference AGM or debug logging.

Questions:
1. Is this a known issue with 26.002.21996 (debug or statistics logging left enabled)?
2. Is there a registry setting, environment variable, or preference that turns this output on or off?
3. Is a fixed build available or planned?

I am having the same issue and when I try to delete the files, they disappear but reappear when I open a pdf document from the same file.

I think that 17 days since the version with this error should have resulted in an update fix by now.
An ETA date should be available by now.

Hello @Meenakshi Negi , is there an update on this issue? I was checking the Acrobat Enterprise Release Notes and I see an update that was posted yesterday. Should we go ahead and install that update? Will that resolve the issue? Thank you

Same issue here with Reader 26.002.21996 32bit.

Noted something that could mitigate this, so that the log files do not proliferate across lots of folders.

**The log files are not created if Acrobat was explicitly open first, and double clicking PDFs only after Acrobat was already open**

Same issue here with Reader 2026.002.21996. Noticed something that could mitigate problem while this is not solved.

**The log files are not created if application is already open**

Open Acrobat first. Then double click PDFs in Explorer as usual to open them at ease.

**Do not double cick a PDF unless Acrobat is already running**

Back from a 2 week holiday and my acrobat auto updated this morning. I am now experiencing the same 2 log files being generated when closing a pdf. I work in Print and use a older plugin that needs 32 bit acrobat. really need a work around as i open and close files constantly all day.
