15.1 upd 6 WinCC RT Professional - The system intermittently stops archiving

alexeveandreis Posts: 10 Rating: (0)	Hello everyone, We have a similar error with version 15.1 upd 6 WinCC RT Professional. The system intermittently stops archiving. Some variables are archived and others are not... after a while it recovers and archives normally until it randomly fails again and recovers again. In the attached image it is marked in yellow as the system stopped archiving some variables but others continued to be archived. All records were enabled for archiving... none were stopped. Any suggestion?

You can see it in the 'Runtime Settings > Logging > Log Segments' section of the project. Above all, it would be interesting to know the elements 'Time period of all segments' and 'Maximum size of a segment'. Also, it would be important to check how many files/segments exist (in total) in the 'Tag Logging Fast', 'Tag Logging Slow' and 'Alarm Logging' folders of the 'ArchiveManager' folder in the project path.
	A rating will be well appreciated.

Check for example the latest WinCC_Sys Logfile to get the last entries. Check if here are some noticable errors or warnings regarding the Taglogging Bye Murof
