I try to shutdown or restart vServer in my Xojo code, but issuing this command, it crash my application.
Here is my code

mVConnection = new VConnection( myHost, myUserName, myPassword, myPort, 5, mySerial )
if mVConnection <> nil then
mVConnection.Open()
mValentinaServer= new VServer( mVConnection )
end if
...
if mVConnection <> nil AND mValentinaServer <> nil then
mValentinaServer.Shutdown << this line crash my application
end if

(for the tests, my vServer is launched with a double-clic on the vserver.app file)
Have I done something wrong ?

Already reported in Mantis (#0008723), but into VALENTINA SERVER

The only workaround I see is :
before issuing vServer.Shutdown, close the connexion and recreate it.

Ok. Narrowed it down and found the origin of the problem :

You have the crash if you insert
csr = mVConnection.SqlSelect("SHOW DATABASES";) (or perhaps other SQLSelect, not tested)
before mValentinaServer.Shutdown :

mVConnection = new VConnection( myHost, myUserName, myPassword, myPort, 5, mySerial )
if mVConnection <> nil then
mVConnection.Open()
mValentinaServer= new VServer( mVConnection )
end if
...

dim csr As VCursor
csr = mVConnection.SqlSelect("SHOW DATABASES")
csr = nil
...
if mVConnection <> nil AND mValentinaServer <> nil then
mValentinaServer.Shutdown << this line crash my application
end if

I just tried with 9.8.1 and the shutdown worked fine (Xojo 2019r3 and Catalina). I used the ValentinaServerUtility project.

The "usual suspects" in information is missing:

- Version Xojo?
- Version Valentina?
- Exception or hard crash?
- If exception which one?
- If hard crash we need the crash log.

I've wanted to implement something similar in the next days, too, so I'm very interested in your exception/crash.
