Just FYI, this issue was seen in 202405 sonic-buildimage |
OK, Can you please paste the full backtrace for the zebra crash? |
Hi @prabhataravind, we took the above PR and we did full OC test run. The issue is not seen. And also, the issue is not reproducible when we tried to reproduce manually even with multiple attempts. |
