All of a sudden my dnn started to become very slow and even ended up in an error message "Server too busy".
I've restarted the IIS several times now (in fact my hoster), played a little bit and figured that simply opening my start page causes at least 130 event logs and all of them are SCHEDULER_EXCEPTIONs or GENERAL_EXCEPTIONs.
Logging on and off gives me 6550 event logs. My page is unuseable at the moment.
I don't want to post all of them here, just two :
