db worker restarts/ crashes when a query takes too long to run

[Will-Cross1]

running nlds find -A -p '.*/(abc){1000}\.txt$' 13 times caused a 502 error and now all normal nlds find commands can't continue

(nlds-client) [wcross@sci-vm-01 NLDS]$ nlds find -A -p '.*/(abc){1000}\.txt$'
Usage: nlds find [OPTIONS]
Try 'nlds find --help' for help.

Error: Could not complete the request to the URL: https://nlds-master.130.246.130.221.nip.io/api/0.1/catalog/find/ (HTTP_502)

then when I try run nlds find -A (even in a different terminal)

(nlds-client) [wcross@sci-vm-01 NLDS]$ nlds find -A
Usage: nlds find [OPTIONS]
Try 'nlds find --help' for help.

Error: Could not complete the request to the URL: https://nlds-master.130.246.130.221.nip.io/api/0.1/catalog/find/ (HTTP_504)

it takes a decent length of time to go back to normal
504 = Gateway Timeout
502 = Bad Gateway

This seems to be because the db query takes too long and it restarts, it causes the db worker to crash with
(at least when this was ran nlds find -1 -p '*/a')
