RMDS Subscription Issue

Hi We currently have a process which subscriber to ric based on user request. Request goes as below
Step 1 : User request for RIC : ABC FID : 1 -> Process would place a view requesting for RIC and FID 1 in response
Step 2 : User request for RIC : ABC FID : 2 -> Process would place a view requesting for RIC and FID 1 and 2 in response
Step 3 : User is not actively looking at the RIC : ABC anymore. Our process would deregister the subscription as there is no active interest.
Step 4 :User at later point expresses interest to look at RIC : ABC. We would then create a new Subscription requesting for FID 1, followed by FID 1 and 2.
We observed when we resubscribe for the ric in step 4, we dont get responses certain time.
Below is how we frame the request in both the cases
private static Triple<OMMPool, OMMEncoder ,OMMMsg> buildRecordSubMsg(RmdsRecordKey recordKey, Set<RField> keys) {
OMMEncoder encoder = subscriptionPool.acquireEncoder();
OMMMsg ricSubMsg = subscriptionPool.acquireMsg();
ricSubMsg.setMsgType(OMMMsg.MsgType.REQUEST);
ricSubMsg.setMsgModelType(RDMMsgTypes.MARKET_PRICE);
ricSubMsg.setPriority((byte) 1, 1);
ricSubMsg.setAttribInfo(recordKey.serviceName, recordKey.ric, RDMInstrument.NameType.RIC);
ricSubMsg = addView(ricSubMsg, keys, encoder);
return Triple.of(subscriptionPool, encoder, ricSubMsg);
}
private static OMMMsg addView(OMMMsg msg, Set<RField> keys, OMMEncoder encoder) {
return addView(msg, keys, encoder, null);
}
private static OMMMsg addView(OMMMsg msg, Set<RField> keys, OMMEncoder encoder, Integer indicationFlags) {
if (indicationFlags == null) {
msg.setIndicationFlags(OMMMsg.Indication.VIEW);
} else {
msg.setIndicationFlags(indicationFlags | OMMMsg.Indication.VIEW);
}
// @formatter:off
encoder.initialize(OMMTypes.MSG, 2000);
encoder.encodeMsgInit(msg, OMMTypes.NO_DATA, OMMTypes.ELEMENT_LIST);
encoder.encodeElementListInit(OMMElementList.HAS_STANDARD_DATA, (short) 0, (short) 0);
encoder.encodeElementEntryInit(RDMUser.View.ViewType, OMMTypes.UINT);
encoder.encodeUInt(RDMUser.View.FIELD_ID_LIST);
encoder.encodeElementEntryInit(RDMUser.View.ViewData, OMMTypes.ARRAY);
encoder.encodeArrayInit(OMMTypes.INT, 0);
Object[] rmdsKeys = keys.toArray();
for(Object key : rmdsKeys){
encoder.encodeArrayEntryInit();
encoder.encodeInt(((RField)key).id);
}
encoder.encodeAggregateComplete();
encoder.encodeAggregateComplete();
// @formatter:on
OMMMsg viewSubMsg = (OMMMsg) encoder.getEncodedObject();
return viewSubMsg;
}

What is the RFA Java version that encounters the problem?
Can you replicate the issue on demand? If so, could you please enable the RFA trace file, replicate the issue and give us the RFA trace file when the problem occurs? The RFA trace file contains incoming/outgoing
messages between the API and TREP server which will let us verify this issue in detail.You
can configure the following RFA Java configurations to enable the log file- <namespace>/Connections/<Connection
Name>/ipcTraceFlags = 7 - <namespace>/
Connections/<Connection Name>/mountTrace = True - <namespace>/
Connections/<Connection Name>/logFileName=<path to log file>
Example:
<node name="rsslConnection">
<map>
<entry key="connectionType" value="RSSL"/>
<entry key="serverList" value="localhost"/>
<entry key="portNumber" value="14002"/>
<entry key="ipcTraceFlags" value="7"/>
<entry key="mountTrace " value="True"/>
<entry key="logFileName" value=".\logs\RSSL_%U.log"/>
</map>
</node>0 - <namespace>/Connections/<Connection
