1. --keyspace doesn't expect any hash file. you cannot specify the hash file when computing the keyspace (remove deshash from you command line)
2. for -l (--limit) you specify the number of restore points to process so for instance -s 11453246122 -l 5726623061 is totally fine because it means start at 11453246122 and continue for 5726623061 restore points within this chunk). in your wrong interpretation of the values that would not be possible because -l would be less that -s, but this is not how -s/-l works, just read --help and the FAQ. so basically -l is the same value for all your nodes, but the start -s would be different for all nodes (start increased by 1/nodes of the keyspace if identical power)
