Knex:warning - Pool2 - Error: ResourceRequest timed out

[nombrekeff]

I've come accross this error, when adding a bunch of jobs, any idea why this could be happening?
I can attach code example if needed.

PD:
It fires event accepted and then fails.

Knex:warning - Pool2 - Error: ResourceRequest timed out
Unhandled rejection Error: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?

This sounds like an issue with better-queue-sql, as better-queue does not require knex.

you have multiple processes that write into same sql file
for example two queues or one queue and one sql database service
