I sincerely recommend filing a support case with your regional ABB support center.
The AC 800M has thread supervision that will detect a blocked thread. There may be many reasons, e.g. a network storm or loop. It's very hard to tell anything more without more information.
Please extract the controller log(s) and possibly also use the AC 800M Fingerprint tool and gather the output (C:\ABB Industrial IT Data\Control IT Data\AC 800M Fingerprint...). The fingerprint tool is available from ABB supportline, or from the SV6 media kit (the tool is backward compatible, at least with version 5.1).
Supply the output to your regional ABB support center when filing the support case with them.
