Problem Statement: This Knowledge Base article answers the following question:
Why every four minutes TSK_DBCLOCK sends the following message to the license server:
IP21ServerUpdateLicenseState - *X_GetIP21ServerLicenseState*
The message can be seen in the TSK_DBCLOCK.OUT file when VERBOSE logging is enabled. | Solution: The communication between the TSK_DBCLOCK and the license server is the heartbeat to ensure the database is still in contact with the License Server.

Problem Statement: Generally an event.dat file is created when the history process, h21archive.exe, is paused or stopped due to file set backups or history system problems. However, there have been cases where an event.dat file is created while the h21archive process is still running. This can happen if data is enterin... | Solution: 1. Check the fragmentation of the hard drive storing the history file sets. Chances are, this drive is badly fragmented, thus creating a performance bottleneck. Data is being collected faster than the history task is able to write to disk. You will need to stop IP.21 and run a defragmentation utility.

Problem Statement: When using standard IP_AnalogDef records, normal behavior is that values written to the IP_INPUT_VALUE field will propagate to the IP_VALUE field, and then be written to history. You might see a situation where the values updating in IP_INPUT_VALUE do not propagate to IP_VALUE. | Solution: One possible cause of this behavior is that compression is activated for the record. If this is not the case then there could be a problem with the IP_BoxcarSlope record. The IP_BoxcarSlope record must be configured for data to propagate from IP_INPUT_VALUE to IP_VALUE even though compression is not being use... |
