1. in your linked youtube video (post #78) you show an example with freezing of the optimization process if you continue an optimization with the new version that has been started with the previous build. Maybe there is an incompatibility between the two builds? What I mean: have you tried a new optimization from scratch with the new build (e.g. enforcing a new test by selecting slightly different input settings)?
2. You say 32 cores; this involves hyperthreading, right? Do you also have sufficient RAM to run so many agents in parallel? I'm having this www.mql5.com/en/forum/327337#comment_14041682 discussion in mind and am wondering if it makes a difference if you don't use all the (logical) cores (which wouldn't answer why build 2190 could handle the job better, but maybe at least worth trying).
Hi at All,
I have another problem with the new version 2280.
In my EAs I use the lib EasyAndFastGUI and from the version 2265 all EAs crash on Start. The problem is into Canvas.mqh, in length of name in
bool CCanvas::Create(const string name, ....
If I delete the new part added ("(string)CharId + ") from name, all return OK
this is interesting; this little test code that has the same string declaration as in CCanvas::Create can't reproduce the error (=compilation + execution without errors with build 2280 beta):
could you nail down which code line in Canvas.mqh exactly causes the crash?My problem was with EA that use GUI (created with lib EasyAndFastGUI.)
In Previous version no problem in compilation and no problem in execution.
From the version 2265, no error in compilation, but crash in onInit during the execution (when it create the gui).
Precisely, runtime crash is due to createButton inside the Combobox that invokes CButton::CreateCanvas -->CElement::CreateCanvas --> CCanvas::CreateBitmapLabel -->CCanvas::create.
In Canvas.mqh, on row 254, the addition of that new part in the name (+(string)ChartID()) makes the name too long (before it didn't happen)
Obviously the problem can be solved by shortening the first part that forms the name of the canva (which should be the name of the EA).

The name of the library does not tell anyone. But I took out and trotted a crystal ball: there is the last article ( https://www.mql5.com/ru/articles/3527 ).
The test example \ MQL5 \ Experts \ Article11 \ TestLibrary16 \ 16_04 \ 04.mq5 works without errors.

Ok, correct, I move into the other discussion. Beyond the library I thought it was correct to report a runtime pb created by the length of the canvas name (which actually grew).

Can you try to rename that file in
04 ProvaCanvasName.mq5
Then recompile and re-execute. You should have a runtime error
Bye

I redid the download and repeated everything (renaming the file 04.mq5 with a longer name "04 ProvaCanvasName.mq5").
It happens exactly as I say, runtime error. The problem is the length of the name of the canvas created (where the first part is given by the name of the EA, which is now longer). It's not the library.
Maybe it only happens to me (but I do not think just because there are threads that discuss the same issue)
With the short name, all is ok.
With the ea renamed:
2019.12.14 16:29:37.364 Experts expert 04 ProvaCanvasName (EURUSD,H1) loaded successfully
2019.12.14 16:29:39.114 Experts initializing of 04 ProvaCanvasName (EURUSD,H1) failed with code 1
2019.12.14 16:29:39.176 Experts expert 04 ProvaCanvasName (EURUSD,H1) removed
Of course there is a problem.
