Reading through the wrapper.log on one of my installations I find some recurrent errors like:
INFO | jvm 1 | 2017/10/13 23:37:30 | ERROR [QueryExecutor[KDV] ] [23:37:30,108]: (id=2538b600) Error occurred while loading tag information. INFO | jvm 1 | 2017/10/13 23:37:30 | com.microsoft.sqlserver.jdbc.SQLServerException: Transaction (Process ID 59) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
INFO | jvm 1 | 2017/10/11 22:31:19 | ERROR [Journal[Journal] ] [22:31:19,052]: Error logging alarm event to the database. INFO | jvm 1 | 2017/10/11 22:31:19 | java.lang.Exception: Unable to add data to memory buffer, buffer full.
Any suggestion? I’m running Ignition 7.8.4, MS Sql Server 2014, Kepware OPC UA Server on some Siemens S7-1500 PLCs.
Thanks in advance,
