We have loaded 100 users in one of the databases and started native database sync so that users get created in One IM DB. But, DBqueue does not process anything and gets stuck. We have enabled trace flag 2453 still no improvement. One more observation is when we run this sync, in task manager we can see that 50-55% CPU is utilized by stdioprocessor. We waited for an hour to check if sync process gets finished but it didnt. Please suggest how can we resolve this issue. We are using version 8.0.
