ISAPI DLL concurrent requests

[Attila Kovacs 617]

Well, I'd clone/backup the project and start removing all 3rd party units, including firedac.

 

- did you check the system/application events?

- if you kill all the w3wp processes in the taskmanager, will then IIS stop faster?

Solved at last. The DLL was hanging due to the call to AddToLog in CloseServer due to the Log thread being terminated at the same time as the call.

 

In the meantime, I had added a TFDMoniFlatFileClientLink component to provide a FireDAC trace to see what was happening with the FDManager as I thought that was causing the problem.

 

Once I'd fixed the problem with the thread log, I still had issues. By a process of starting from scratch (as you suggested) and adding units/components as I went along, I eventually managed to narrow it down to the FlatFile component. Once I removed it, all was well. Must be a threading problem or some such.

 

Many thanks for your help
