1950648 - Error: Stream Events_observer, got fatal error EVID_COMMUNICATOR_HALTED in LMS 6.1 preprocessor

When LMS system was started as normal after some time of stable functioning, LMS operation stopped and the errors below were observed.

1. Preprocessor.log file contains this message :
[ERROR] PP: Stream Events_observer, got fatal error EVID_COMMUNICATOR_HALTED.

[INFO ] PP: SHUTDOWN REQUESTED, EXITING...

instead of the expected message : [INFO ] PP: Ancestry initialized

with no information after this in the log.

2. In the Platform.log file: 

[SP-02-108063] (151.342) sp(12957) GatewayClient::postToSubscriberQueue(646:163) time to drain base data 80882 ms exceeded limit 80000 ms, dropping client connection.
[SP-03-132000] (151.364) sp(12957) StreamExport(Events):: dropped a subscriber (via processed message).
[SP-03-132000] (151.374) sp(12957) StreamExport(Events):: dropped a subscriber (via processed message).
[SP-04-108001] (151.386) sp(12957) GatewayClient(646:163)::~GatewayClient() destroyed (auto).
[SP-03-132000] (15055.741) sp(12957) StreamExport(PreprocessorTransactions):: dropped a subscriber (via processed message).

The consequence was that the preprocessor wasn't working as usual.

When the preprocessor is restarted, the preprocessor returns to its normal state, working without errors.
