Memory Leaks in 9.1.1

[Plastic]

We upgraded to 9.1.1 recently and was put into production in Azure.  Immediately we started to have memory usage issues and a memory dump showed lots of event handler leaks possibly deep in the Telerik code.  We reverted back to 8.1.1 and so far are not seeing any of these eventhandler leaks from Telerik.  Just curious if this is a known issue or if others have experienced this.

Hello,

You are the first one who report to us such an issue. Based on the attached screenshot, it seems like there is some issue in the ColumnMenu context that causes the memory leak. To troubleshoot it further on my side, could you please provide the full call stack of the encountered issue? This will allow me to investigate more thoroughly and pinpoint the scope of the problem. Also, if possible, please provide me with a small isolated code snippet with the configuration you are using.

Thank you for your cooperation. I look forward to your reply.

Regards,

Tsvetomir,

 

I am not sure what to give you.  We don't really have any code that explicitly references the ColumnMenu on those pages.  I'll see if I can find something in my memory dump that can pinpoint a call stack.

We have been running on 8.1.1 since Monday and our memory has not jumped over 50% and when I did a memory dump, there were no ColumnMenu EventHandler leaks reported in the dump.

Hello Mark,

Within this REPL link, I'm sending you basic Grid configuration with column menu. Can you please run it on your side and let me know if the issue can be reproduce in it? If yes, please provide some steps, which helps you to reproduce the issue, or make a screen recording where the issue is encountered. If cannot reproduce the issue in the provided example please modify it to reproduce it and send it back to me for inspection.

This will allow me to investigate further the issue you are encountering.

I eagerly anticipate hearing back from you.
