It is not needed to see the memory operations logs. Just to dump the
chunks in memory.
You would need ctl and ctl_rpc modules (iirc -- they should be in the
default config file), then run:
kamcmd cfg.set_now_int core mem_dump_shm 1
Extract the logs of the dump from the shared memory and send them over.
Send also the output for:
kamctl mi get_statistics shmem:
Cheers,
Daniel
