How to resolve Error in 'similarity' command: External search command exited unexpectedly with non-zero error code 9?

[soheil115]

I use nlp-text-analytics app for similarity between two strings but I get above error

when I run lines 1, 2, and 3, it gives a result of about 14,973,764 (3814*3926)

It is interesting that if I reduce the data, for example, the output of the third line is  13.348.400 (3400* 3926 )  , it does not give an error and the result of the fourth line is returned.

This means that the similarity command has problems with data above 13.5 million

my splunk is 8.2

nlp-text-analytics 1.1.3

python_upgrade_readiness_app  4.0.2

The similarity command is not standard.  What app did it come with?

Have you looked at the search log to see if there are more details that might explain the cause of the error?  Find the search log by opening the Job Inspector then scrolling down to the bottom and clicking on the "search.log" link.

Based on the error code, I suspect you're running into a limitation, probably memory, but the search log should have that information.

Also check /var/log/messages for OOM killer messages.
