Daniel, thanks for explaining the root cause of the problem. The developers have the code 'fixed' for 8.5.2 and probably for the first fixpack (haven't verified, but am pretty sure). The ini setting can then be removed, the efficiencies will be there and the misbehaving extensions can still misbehave without hurting the server.

I would love to know which versions of which extensions are not strictly following the C-API, so we can ask the developers to better their ways.

@ Lars, I cannot give you names or examples. But I am in contact with a couple of larger ISVs who take care about doing the right things and we are discussing offline.

I cannot name any partner in public without their permission. And the partners I spoke with on development level are concerned doing the right thing.

I am posting this info for other partners to get concerned and maybe start discussing about it offline or in public if they like to.

What's not clear from your post is that you say:

"The problem seem mainly to occur when Extension-Managers use NSF or other C-API calls in the init phase of the DLL (MainEntryPoint)"

But an extension manager is a dll and it does not implement any MainEntryPoint function. I guess that instead of MainEntryPoint you tried to say DllMain. Is my assumption correct? Because else maybe you tried to say that server tasks cannot make API calls in MainEntryPoint but I don't think so!

Thanks

@Lars: It's an opportunity for you to test those ISV having this problem to see the time it takes to fix this issue. Better if they already fixed it or if they don't have it, but if they have it now then it's an opportunity for you to test the support.

@Pablo

DLL_EXPORT STATUS LNPUBLIC MainEntryPoint( void ) or however you name it is the routine that is invoced when the DLL is loaded.

This is also the place where you register which EM events are invoked.
