Hi
As general practice go to SMQ2 in CRM, you will get lots of queue in the name of R3AD_CUSTOMER*.
Double click on this queue you will get an error message.
Than press F6 (some times queue will move some times not), then select queue which is in error status click on delete button then refresh it.
Then click on Back button and select your queue click unlock queue and press refresh button this is general practice.
By doing this thenumber of queues will come down and go to SMW01 refresh all intermediate state bodcs either process or it will be in error status.
Best of luck
Regards
