Vcenter SQL Query eating CPU resources

$

Do anyone else have a problem with a SQL query in the Vcenter database eating up a lot of CPU resources?

 

We noticed that almost all the time one CPU core is 100% utilized by the SQL server, digging deeper we found that it's always the same query running over and over again:

SELECT DISTINCT                         VPX_SCSI_LUN.UUID AS lunUuid, CASE VPX_HOST_BUS_ADAPTER.VPX_TYPE WHEN N'vim.host.BlockHba' THEN CAST(VPX_PSA_PATH.HOST_ID AS VARCHAR(255))                         + '-' + VPX_SCSI_LUN.UUID WHEN N'vim.host.ParallelScsiHba' THEN CAST(VPX_PSA_PATH.HOST_ID AS VARCHAR(255)) + '-' + VPX_SCSI_LUN.UUID ELSE VPX_SCSI_LUN.UUID END AS scsiVolumeEntityId,                         VPX_DATASTORE.NAME AS datastore, VPXV_DS_LUN_INFO.DATASTORE_ID AS datastoreEntityId
FROM            VPX_DATASTORE INNER JOIN                         VPXV_DS_LUN_INFO INNER JOIN                         VPX_PSA_ADAPTER INNER JOIN                         VPX_PSA_PATH ON VPX_PSA_ADAPTER.HOST_ID = VPX_PSA_PATH.HOST_ID AND VPX_PSA_ADAPTER.KEY_VAL = VPX_PSA_PATH.ADAPTER_LINK_KEY INNER JOIN                         VPX_PSA_DEVICE ON VPX_PSA_PATH.LUN_LINK_KEY = VPX_PSA_DEVICE.KEY_VAL AND VPX_PSA_PATH.HOST_ID = VPX_PSA_DEVICE.HOST_ID INNER JOIN                         VPX_HOST_BUS_ADAPTER ON VPX_PSA_ADAPTER.HOST_ID = VPX_HOST_BUS_ADAPTER.HOST_ID AND VPX_PSA_ADAPTER.LINK_KEY = VPX_HOST_BUS_ADAPTER.KEY_VAL INNER JOIN                         VPX_SCSI_LUN ON VPX_PSA_DEVICE.HOST_ID = VPX_SCSI_LUN.HOST_ID AND VPX_PSA_DEVICE.LINK_KEY = VPX_SCSI_LUN.KEY_VAL ON VPXV_DS_LUN_INFO.UUID = VPX_SCSI_LUN.UUID AND                         VPXV_DS_LUN_INFO.HOST_ID = VPX_PSA_PATH.HOST_ID ON VPX_DATASTORE.ID = VPXV_DS_LUN_INFO.DATASTORE_ID
WHERE        (VPXV_DS_LUN_INFO.DATASTORE_ID IS NOT NULL)

Anyone else noticed this problem with Vcenter 5.5 Build 2183111 (Update 2) and MSSQL 2012 SP2 + CU2 ?
