Hello,
We have ongoing issue on our Production Servers. We have DF key with 250 users allowed. However, from time to time, entire system going stuck. And what is more strange - we do not have 250 users on the Production Server (in a peak time we have 100 max)!
We monitored and examined this issue. It seems like it happen when all licenses are in use and DataFlex can not start any of applications.
Also, we found, that orphan VDFDAEMONs remains in some cases when application was abnormally terminated.
When Task Manager is reviewed, we can see 40-50 VDFDAEMON.EXE processes that are sitting in the memory. When all of these processes are killed, system starts to work again. Another option is to reboot the System (not the best solution though as it starts 10-20 minutes and users become angry).
I have no idea what we can do about this, but first step would be a monitoring. Is there a way to identify somehow - how many DF users (Licenses) are available on the System and how many currently in use? It would help a lot.
Any input WELCOME!
Regards,
