today I had to realize, that our workflows, which are running for years, are not starting anymore when creating a new list item.
Our system administrator told us, that wether patches were installed nor changes were applied to our systems.
Can you give me some advices where to look at?
I have tried to increase the log level to verbose, but I couldn't find any hints regarding the problem.
I don't get any error messages, it just won't start.
