Nah! what you can not process easily you can not interpret at that scale.

If there are 6 code paths which are passing NULL to dict_ref. All of 
them use msg-id LG_INVALID_ARG in the log file. To figure out the uniq 
code paths the command is:
"grep LG_INVALID_ARG <log-file> | grep dict_ref | sort | uniq -c"

Assume the log is 20GB. And there are 100000 dict_ref logs. What will be 
the command to get the info above after this change is merged?
