SLNet deadlock on DMA startup
Affected versions
- DataMiner 10.1.0 up to 10.2.0 [CU15]/10.3.0 [CU3].
- DataMiner 10.1.2 up to 10.3.2.
Cause
In a DMS using a Cassandra cluster setup, when multiple DataMiner Agents are started at the same time, a deadlock can occur in the SLNet process.
Fix
Install DataMiner 10.2.0 [CU16], 10.3.0 [CU3], or 10.3.3.
Workaround
Stop any DMAs that do not fully start up and start them up one by one.
