Situation: WebBrowser control to visualize a treeview structure, Powerbuilder 2019 R3 build 2670

I'm using Bootstrap Treeview 4.0 and anytime I visualize a new structure, memory occupation of pbcefclient.exe grow until proces crash (270MB). Sometimes pbcefclient.exe don't crash but Powerbuilder freeze.

There is any method to release memory?

If I use Powerbuilder 2022 build 1892 memory grow but the proces don't crash. Anyway, if memory grow too much, will crash also in PB 2022, I suppose

 

Thanks

Hi Ricardo;

  Why are you using a 3rd party control (where you have no control over O/S resources ) vs using either PB's built-in Treeview Control or PB's Treeview DataWindow?

Seems there is problem with the JS code of the third-party TreeView control you are using the memory should not keep growing. Since you are having same problem on PB 2022 that is newer version of Chromium Web browser engine so I don't think it is bug of the Webbrowser control.

It doesn't seem to me the problem is the TreeView control. Take a look at link Riccardo provided that CEF may have memory leak with ExecuteScriptAsync function there is simple example has nothing to do with TreeView. I think Appeon engineering team should take a look at this to see if updated version of WebBrowser engine will resolve this and make sure the problem is not in the PB layer.
