Can't activate more than 1 Bacnet IP datasource simultaneously

[nduvernois]

I have about 130-140 BacNet IP datasources, but as soon as 1 is active, I can't activate the other, and neither can I discover new datapoints in the active datasource, or in any other. This is the same behaviour as in ScadaBR.

For example, after a Tomcat restart, I find this in the event list : 8:57:11 : 'B519 sous-station': Initialization error: Address already in use: Cannot bind Well, actually, there is no other datasource with the same IP address.

Steps to reproduce the behavior: Datasources have been initially created in ScadaBR, and the MySQL databased has been dumped to disk and imported to MySQL 5.7

1. only one BacNet IP address is active
2. in datasources management, click on any other database to activate it

Configuration

OS: Windows Server 2016 Browser : Chrome Releases: ScadaLTS 2.6.13, Apache Tomcat 9.0.59, MySQL 5.7.19 I also noticed the same behaviour with ScadaLTS 2.5.1.

Log from tomcat9-stdout: INFO 2022-03-29T08:57:12,082 (com.serotonin.mango.rt.RuntimeManager.initializeDataSource:378) - Data source 'B519 sous-station' initialized I have not found anything relevant at the same timestamp in catalina, tomcat9-stderr or localhost logs.
