@C_R 

Thanks for trying, This is very strange, Why some get this crash and some do not.  I have no idea what is going on. May be someone will figure it out.

I'll try to turn on tracing and see if I can find something new.

@C_R 

I noticed you do not have Physics updates installed on your system. This could be the difference., I do not know. Try with Physics updates installed with latest version and see.

@ecterrab 

FYI, I've added two movies in my post.  I see you are using mac OS. I am on windows. This could be the difference.

my ini file has only one command which just prints the process id. Nothing else.

Please see updated movies. Another person above was also able to reproduce the crash on windows.

@acer 

" Does it crash if you force only method=contour? "

Yes, It still crashes.

u:=Int(2/3/alpha^(3/2)*sin(1/2*3^(1/2)*ln(alpha))*sin(alpha)*3^(1/2),alpha=0..x,method=contour);
value(u);

#server crash

@acer 

How does one check "without Physics update"? Other than removing it from libname, how to check? I tried below removing Physics update lib from libname, but crash still happens.

@acer 

That is correct. verified on Maple 2024

integrand:=(2*x^2022+1)/(x^2023+x);
convert(integrand,parfrac);  #kernel crash

Ah!  I found the problem. few days ago I asked about expansion of exp here Why-Maple-Likes-To-Write-Exp2a-As-expa2-

So I used the suggestion in one of the answers

"There's also a way to suppress the expansion of exp (or any other function) that maintains the suppression until you turn it off; so it's suitable for use in an initialization file:

expand(expandoff()): expandoff(exp):"

And edited my Maple ini file and added the above. Now that you mentioned ini file, I removed the above and the problem is now gone. 

So that was the cause. Here is worksheet that shows it is fixed now after removing the above from my ini file

I had no idea that disabling expansion of exp will cause such internal issue. Thanks for everyone's comments and answers.

@Carl Love 

opps. fixed it now. Was sleepy and did not notice.

@Ronan 

Thanks. But I tried RealDomain and it did not work for me. The code is still on my screen. Here it is

What is the difference between what I did above and what you did for it to have worked with you?

The strange thing, is that in Mathematica by default it works in complex domain. Maple should be the same. But Mathematica gave x=a^(2/3) as only solution without saying real domain.

It looks like when I used solve() with real domain, it works. But when using PDEtools:-Solve with real domain, it does not work!  is this a bug?

I know about simplify(size) ofcourse but I stopped using it long time ago. I had mixed results from it. Sometimes it gives worst result than just simplify. Here is just one example out of 100's I have

You see the simplify size gives result almost twice as large are just simplify in this example !

I understand that simplification is not easy in CAS. I think it is one of the hardest things to get right, but also simplification in CAS is one of the most important core functionalities. So important to get it right.

It is 50% science and 50% art and there is no one algorithm to follow each time as what is simpler can by a fuzzy concept.

I am finding the best thing is to reduce as much calling simplify and its friends or always check after calling simplify to see if the result should be used or not using some more tests.

It looks like my method is not general and does not work for all cases. May be a iterative solutions as you have is simpler than trying to find short cut.

@Thomas Richard 

I did not see the check to turn off infinite scroll and neither did the OP. May it should be off by default?

But when I turned it off, how does one go to "next page"? I see no next page arrow any where to click on.

So user can only now see the first page.

Is this by design or is there a trick to go to next page while infinite scroll is off?

fyi;

I am seeing this alot in Maple 2024. Twice now in one day.

Unfortunately, like in Maple 2023, it is random where it happens. So can't make MWE. Just wanted to let you know it is still there in Maple 2024 and seems more frequent also.

interface(version)

 Standard Worksheet Interface, Maple 2024.0, Windows 10, March  01 2024 Build ID 1794891

Since that is the only message Maple gives, it is impossible for a user to know what caused it.

Hopefully sometime during this decade Maplesoft will be able to figure what causes it.

I did not know that Maple uses python and installs it own python. But if Maple does use Python internally for some things, it makes complete sense for Maplesoft to install its own Python and not use or depend on an external system level one.  

Do you know since which version Maple started using Python? I know Maple uses Java ofcourse but did not know it also needs Python to run.

@Kitonum 

You seem have a bug

            IsSameOrder([7,2,4],[7,4,2,7,2,4])
                           false

but it should be true, since 7,2,4 do show in same order. This is how I understood it. May be your implementation made assumptions different.
