The task responsible for requesting a wait_for_grant on sequencer for sequence has been killed, to avoid a deadlock the sequence will be removed from the arbitration queues

In reply to kranthi445:

You are doing strange and risky things. My recommendation you should NOT kill your sequences.
Select the right arbitration mode for the execution of your sequences.

The mode
UVM_SEQ_ARB_RANDOM
seölects the sequences you want to execute in random order this might solve your problem in an easy way.
