When you open a PDF file in Adobe Acrobat/Reader you may notice that the client reads the following registry keys repeatedly:
The result of reading these keys if often BUFFER OVERFLOW. It’s unnecessary for Acrobat/Reader to access these registry keys multiple times when opening a single PDF file. If you’re using Terminal Server environments, where only one client services multiple users, this issues can lead to performance degradation.
Update to Adobe Acrobat/Reader 9.4 or X.
It’s common for a BUFFER OVERFLOW to occur when reading registry keys on application startup. This error doesn’t necessarily point to a memory issue in Acrobat/Reader. Adobe Acrobat/Reader 9.4, X and later have been updated to access these keys only once when opening a PDF file. The number of BUFFER OVERFLOW events is therefore also reduced.
