Inconsistent behavior while adding BMCSimulator as a server to ODIM

[rohitkumar-ro]

Description:

We are trying to add BMCSimulator in ODIM as a server 3 out of 5 time we are receiving 503 response which is blocking to use BMCSimulator in ODIM github action to perform basic sanity test

Steps to reproduce:-

step 1:- Start the BMCSimulator with below comaand after modifying the Simulator.json file with required changes

simulator file content:
{
"binding": {
"ip": "<VM_IP>",
"port": 45000,
"odimUrl": ""
},
"security": {
"server": {
"useTLS" : true,
"basicCredentials": "admin:admin",
"externalKeyStoreLocation": "/home/odim/BMCSimulator/bmc.keystore.jks",
"externalKeyStorePassword": "Bm@_store1",
"useServerMTLS": "false"
},
"trustStore": {
"externalTrustStoreLocation": "/home/odim/BMCSimulator/bmc.truststore.jks",
"externalTrustStorePassword": "Bm@_store1"
},
"httpClient": {
"withBasic": true,
"basicCredentials": "admin:admin",
"useTLS" : true,
"serverCertificateVerificationEnabled": true
}
},
"cache": {
"etags": false
},
"resourcesConfig": {}
}

Cmd to start BMCSimulator:-
nohup java -jar simulator-runner-1.0-SNAPSHOT.jar run BMC -c /home/odim/BMCSimulator/src/main/resources/simulator-config.json >> /home/odim/simulator.log 2>&1 &

log after executing above command:-

odim-controller:~$ netstat -tulnp

Step 2:- Add the the BMCSimulator to ODIm using the below POST command

curl -i -s -k -X POST -H "Authorization:Basic YWRtaW46T2QhbTEyJDQ=" -H "Content-Type:application/json" -d '{"HostName":"<VM_IP>:45000", "UserName":"admin", "Password":"admin", "Links":{"ConnectionMethod": {"@odata.id": "/redfish/v1/AggregationService/ConnectionMethods/'$grfConnectionMethodID'" }}}' 'https://'<VM_IP>':30080/redfish/v1/AggregationService/AggregationSources/'

Step 3:- Do a get on the task id to and check for 201 response for successful server addition with below command

curl -o /dev/null -s -w "%{http_code}\n" -s -k -X GET -H "Authorization:Basic YWRtaW46T2QhbTEyJDQ=" 'https://'<VM_IP>':30080'$bmctaskid''
