Thank you for reporting this issue, we need more details to trace it. Would you please provide:

  1. Hixl or CANN version.
  2. Mooncake version or commit SHA.
  3. Detailed core dump and Mooncake logs.

Notes: I previously encountered a similar problem , but I'm not sure if it's the same one. In my case, I solved it by changing the memory allocator to jemalloc, maybe you can have a try.
