We've been using VC for 2 years now without an issue. As soon as we upgraded to 8.2.3, the service crashes every day at the same time.javascript:insertsmiley('🤬 ','/Images/Emoticons/msp_cursing.gif')

In the Windows server event viewer, I've typically seen the following series or events:

JobAPI->Save->Saving Jobs (158) - in shut down: False

Then:
Application: VisualCronService.exe

Then:

Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000

Faulting package full name:
Faulting package-relative application ID:

And the service shuts off. We've since changed the service to recover by having Windows restart it. I'm trying to figure out the root cause so we don't have to worry about a possible recovery scenario. Are there any internal settings to check to identify why it's breaking at the same time? Or some possible combinations of server settings that could conflict?

Thanks.

Hi,

thanks for the report. This problem has been fixed in 8.2.4. It is related to KeepAlive for SFTP connections.
