Exchange server 2013 CU7 - RelinquishedWlmStall While importing PSTs into the mailboxes

Hello,

I'm trying to more than 5 import psts into the mailbox server Exchange server 2013 CU7. Only 1 is active and rest all are in the state of RelinquishedWlmStall.

StatusDetail: RelinquishedWlmStall

Message: Informational: The request has been temporarily postponed due to unfavorable server health or budget limitations. MRS will attempt to continue processing the request again after

I have other two servers exchange 2013 with SP1, there are no issues on those servers. 

All the three servers are in DAG and if the database is active on CU7, i'm facing issues. I guess some changes were done on WLM level.

I have increased the values in the MRS configuration file as below and restarted the service, still facing the issues.

Do we have to change the WLM App settings? Resources are huge: 64GB RAM, octa core processor.

Exchange is limiting it somewhere, how do i change it? Its only on-premises exchange server no hybrid.

MaxActiveMovesPerSourceMDB="50"
    MaxActiveMovesPerTargetMDB="50"
    MaxActiveMovesPerSourceServer="250"
    MaxActiveMovesPerTargetServer="250"
    MaxActiveJobsPerSourceMailbox="50"
    MaxActiveJobsPerTargetMailbox="50"
    MaxTotalRequestsPerMRS="250"

MaxMRSConnections="250"

Default App settings in the same file:-

<appSettings>
    <!-- Mdb latency health threshold values in msec.  Valid range is from 0-1000. -->
    <add key="MdbFairUnhealthyLatencyThreshold" value="20"/>
    <add key="MdbHealthyFairLatencyThreshold" value="10"/>
    <!-- Maximum delay that WLM returns under "Fair" database resource health in msec. Valid range is from 0-60000 -->
    <add key="MdbLatencyMaxDelay" value="60000"/>
    <add key="LogEnabled" value="true" />

Hi,

Since this error only occur when the database is active on the database in Exchange 2013 CU7, then I suggest to check the content index on this database.

Get-mailboxDatabaseCopystatus "DB on CU7"

If the content index status is unhealthy, we need to fix it first.

Best Regards.

Thanks for the response.

There is no problem with the Content Index, if there is, it would report the status as something like stalledduetoCI.

Do you know Is there a bug in CU7 which is throttling the mailbox imports? Only 1 mailbox is being imported at one point of time, rest all are going to "RelinquishedWlmStall"

Is there any bug in CU7 or some throttling need to be adjusted? probably through WLM?
