We installed new version our application with Infra 11.2 and it wasn’t helped. We don’t use multithreading.
What can we do to fix this issue? Reinstall frameworks? Put Infra dlls in GAC? etc. It is so critical for our client and us. Please advise.
As much as I want to, I cannot tell many from this information. Could you please tell me what is your scenario, what steps do I need to follow in order to reproduce that issue?
It would be even better if you could provide a small sample project which reproduces the issue.
We have a lof of clients but this issue reproduces only on one.If client restarts his PC this issue doesn't reproduce some time.But it happens again after 0.5-4 hours and client must restart his PC.All of our forms with Riboon core. Exceptions are the same.We reinstalled FrameWorks on client's PC. We don't know result.I remember that other our client had the same problem about year ago.We reinstalled FrameWorks on his PC. It wasn't helped. Client reinstalled OS b/c he couldn't use our CRM system.It's very bad situation for us.
Of course I can't create sample project.
Do you have any ideas how can we help to our client?We don't want to reinstall OS...Thanks.
