Hi Anton,

I haven't had a chance to try the patch you mentioned yet.
But this fix 
<https://github.com/ilbers/isar/commit/ed2f8fda7cc85309c4f9a1f49a3f4b96df9886bb> has 
greatly reduced the error frequency on our side.

As Cedric mentioned, we also have managed servers and several IT services 
that might cause such issues.
That's why, I can say that we have achieved acceptable stability for now.

Thanks,
Gokhan
