Errors in wrapper.log

Ignition
#1

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.

and

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? Iā€™m running Ignition 7.8.4, MS Sql Server 2014, Kepware OPC UA Server on some Siemens S7-1500 PLCs.

Thanks in advance,
regards

Here is a StackOverflow thread that can hopefully give you some insight regarding the SQLServerException:

By the way, the free WrapperLogViewer project might be useful to you. It enables you to see the wrapper.log file from an Ignition client. More info here:
