[Magma-CDC] Segmentation fault in magma_Dump

Steps To Recreate:

1. Create a 3 node cluster
2. Create a magma buckets with (bucket_history_retention_seconds=1500,bucket_history_retention_bytes=99000000000,) (vbuckets = 16, replicas = 2)
3. Create 14 collections(total collection count is 15, including default collection)
4. After creating collection update the collection history setting to true
5. Create 5 million docs in each of the collection
6. Upsert all the docs
7. Again start upserting all the docs
8. While doc ops are going on reduce the replicas to 1 and change fragmentation to 30% trigger rebalance @ 6:11:36 AM
9. Again change the replicas to 2 and trigger rebalannce(6:13:20 AM)
10. Immediately after above step tried magma_dump command and observed segmentation fault(@ 06:14:30 2023 from dmesg)
    (Tried on node 172.23.107.76) (Would be helpful if we can have minidump facility for magma dump, I tried attaching gdb after this but no luck in reproducing this)
