This warning is triggered when handles in use exceeds the handles warning threshold set in Accredo > View > Preferences > Trouble-shooting tab.
Usually the warning thresholds would only be set while trouble-shooting an issue with handles being exhausted and returning Windows error 1158. The aim is to identify what is causing the exhaustion, which may simply be too many forms left open or may be something using and not releasing handles.
There are 3 different limits on allocating User Handles in Windows - a per process 10,000 limit, a global 32,700 limit and also a total size limit in the User heap. Exhaustion of any of these can cause error 1158. A warning set to 9000 is suggested as a starting point for trouble-shooting.
Handles in use are shown in Accredo > File > Diagnostics > Machine tab.
Forms and Modules Accredo is using handles for are shown on the Modules and Forms tabs in Accredo > File > Diagnostics.
Check those to see if there is anything repeating over and over. Note how many of each, and number of handles from Machine tab.
Close all forms - Window > Close All, then open the Diagnostics form again. There will be a limited number of both Modules and Forms, note and check handles use again, it should be under 1000 at this point but varies by what modules they have, and what Windows is using for printers etc.
Handles (aka Kernel Handles), User objects (aka User Handles) and GDI objects (aka GDI Handles) can be customised into Task Manager > Details view via add columns so these can be seen outside Accredo.
There are also three MaxBasic functions - GetUserHandles, GetGDIHandles, and GetKernelHandles available for scripts to track increases in handle use across operations.
