Bug

Description/Steps to reproduce

We use Loopback 3 together with an Informix server. If a lot of create, update and delete request occur at the same time, our Informix server sometimes gives the following error and node crashes:

Sep 21 09:32:34 node[7626]: Error: [IBM][CLI Driver] CLI0126E Operation invalid at this time. SQLSTATE=HY011 Sep 21 09:32:34 node[7626]: at Error (native) Sep 21 09:32:34 node[7626]: at Database.setIsolationLevel (/node_modules/loopback-ibmdb/node_modules/ibm_db/lib/odbc.js:1151:21) Sep 21 09:32:34 node[7626]: at /node_modules/loopback-connector-informix/lib/transaction.js:61:22

I do not know the cause of the Informix error, but I think the crash of Node can be prevented.

Expected result

Node does not crash.

Additional information

node -e 'console.log(process.platform, process.arch, process.versions.node)'

linux x64 6.14.3

npm ls --prod --depth 0 | grep loopback
