KnexTimeout errors in Central

Apologies for jumping in on the thread here...

One of our servers running 1.1.2 is failing intermittently with Knex timeout errors. Service docker log:

mservice  | KnexTimeoutError: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?
mservice  |    at Client_PG.acquireConnection (/usr/odk/node_modules/knex/lib/client.js:348:26) {
mservice  |  name: 'KnexTimeoutError',
mservice  |  sql: undefined,
mservice  |  bindings: undefined

Upgrade to Central v1.2? We switched out the database layer (because of some of these intermittent issues).

Many thanks, Yaw. I've now updated our Central servers to 1.2 - we'll monitor and let you know if there are any recurrent issues.
