AD System Discovery causes crashdumps

Last week I was confronted with the fact that smsexec services was collapsed at one of the ConfigMgr servers. My first thought was to analyze the server logs. What struck me was the presence of the crash dumps folder. This corresponds to the new crash dump sub-directories wich contains smsexec as part of the description.

The crash.log pointed me to Active Directory System Discovery as the culprit. When checking the AD System Discovery properties, I discovered a typo of a custom attribute pwdLastSt.

After corrected typo (pwdLastSet) and run an AD System Discovery cycle…no crashdumps anymore :-) Problem solved!
