Hello EO Support Team -
We upgraded EO.WebBrowser, EO.WebBrowser.Wpf and EO.Wpf to version 22.1.67 and started receiving this error. Please find the error details below
Failed to start image manager
at EO.Base.Runtime.nptm(Object lsy, Exception lsz, Boolean lta)
at EO.Internal.tsdj.kkdj.jyuf()
at EO.Internal.tsdj.kkcz.mlwk(Boolean nnj)
at EO.Internal.tsdj.kkcz.mepj.ihlc(Object nno)
at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state)
at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()
at System.Threading.ThreadPoolWorkQueue.Dispatch()
at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()
We are not sure the root cause of this issue. We have never seen this in the previous versions.
We would like to know why we are getting this error all of a sudden and how do we resolve this?
Any of your help would be much appreciated.
Thanks

Hi,
Where/when do you see this error message? Do you see any other functioning error when this error occurs?
This error can occur when application shutdown and is more often observed in Azure environment. We have added code to automatically restart the "image manager" process when it has exited. However this can "naturally" occurs during the system shutdown or resource recycling. In that case restarting would fail but it should not impact your application functionality because the system/process is being shutdown anyway.
In our next build we will add more code to check whether a shutdown is in progress and in that case we would not attempt to restart image manager. That should eliminate some of these errors.
However if you observe this error during normal usage of your application then please try to call EO.Base.Runtime.GetLogs to collect runtime logs after you receive this error and send the log to us. Once we have that we will see what we can find.
Thanks!

Thanks for your quick response. We see this error message every time when the application is being shutdown.
Please let us know when you add the code to avoid this error.

Hi,
This is just to let you know that we have posted a new build that should resolve this issue. You can download the new build from our download page.
Please note that this is the first build of the 2023 release cycle. So it requires a different license key. As such make sure you update your license key first.
Thanks!
