OmmConsumer reopens all RIC streams every 15 seconds

HI,
We have omm consumer, connecting to omm interactive provider.
Everything looks good, except that consumer every 15 seconds reopens every stream, regardless whether consumer received any data recently or not. "Reopen" looks like a sequence of closeMsg and requestMsg sent at the same time. Example of the log is below.
Does anyone know what is causing this behaviour?
Thank you.
In this example timeout is set to 5000 milliseconds, which triggers reopen faster:

The refresh message of the TXU9 item doesn't have the refresh complete flag.
<refreshMsg domainType="RSSL_DMT_MARKET_PRICE" streamId="4" containerType="RSSL_DT_FIELD_LIST" flags="0x28 (RSSL_RFMF_HAS_MSG_KEY|RSSL_RFMF_SOLICITED)" groupId="0" dataState="RSSL_DATA_OK" streamState="RSSL_STREAM_OPEN" code="RSSL_SC_NONE" text="Refresh Completed" dataSize="31">
The refresh message must have the refresh complete flag like this.
<refreshMsg domainType="RSSL_DMT_MARKET_PRICE" streamId="4" containerType="RSSL_DT_FIELD_LIST" flags="0x1E8 (RSSL_RFMF_HAS_MSG_KEY|RSSL_RFMF_SOLICITED|RSSL_RFMF_REFRESH_COMPLETE|RSSL_RFMF_HAS_QOS|RSSL_RFMF_CLEAR_CACHE)" groupId="1" qosDynamic="0" qosRate="1" qosTimeliness="1" dataState="RSSL_DATA_OK" streamState="RSSL_STREAM_OPEN" code="RSSL_SC_NONE" text="Item Refresh Completed" dataSize="64">
The description of the refresh complete flag is:
