Symptoms

MCS does not start with the errors seen below: at com.rabbitmq.client.impl.AMQChannel$BlockingRpcContinuation.getReply(AMQChannel.java:343) at com.rabbitmq.client.impl.AMQChannel.privateRpc(AMQChannel.java:216) at com.rabbitmq.client.impl.AMQChannel.rpc(AMQChannel.java:202) at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:347) ... 19 more Caused by: java.io.EOFException at java.io.DataInputStream.readUnsignedByte(DataInputStream.java:290) at com.rabbitmq.client.impl.Frame.readFrom(Frame.java:95) at com.rabbitmq.client.impl.SocketFrameHandler.readFrame(SocketFrameHandler.java:131) at com.rabbitmq.client.impl.AMQConnection$MainLoop.run(AMQConnection.java:515) Administrator Server startup failed at Tue Aug 08 12:33:20 EDT 2023: Closing all connections to database. Node start failed. Starting REST API Service.... REST API Service startup failed. Start MC Rest: processing time = 10 s.

Cause

The root cause is being unable to connect the RabbitMQ dynamic shovels with a DPC that is monitoring Avamar at the time that MCS is starting.

Resolution

Temporarily disable the BRM service by setting the following parameter to false in mcserver's xml configuration file. /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml Start MCS. Because a DPC is likely set to monitor the Avamar, the DPC automatically sets the key "enableBrmService" back to true after MCS starts.
