Description
Build 6.5.0-4282
Observed following panic while running Plasma DGM performance tests.
Note that till now we ran 5 DGM tests with similar workflow but only 2 tests shown this panic.
Workflow of test-
1. Build an index which goes in DGM(~50% RR)
2. Run incremental phase(only KV ops, no scans) twice
3. Run index scans and KV ops, measure latency/throughput
