Hi,
I am using splunk db connect version 3.1.4 and I am getting below error for sourcetype=dbx_server -

I actually ran into this last night and found a fix that I thought i would share. Basically the way i understand it is that the database has a DateTime field that is empty and the java driver doesn't like it. So you can add a parameter to the jdbcUrl to tell it to covert them to Nulls like so:

jdbcUrlFormat = jdbc:mysql://<host>:<port>/<database>?zeroDateTimeBehavior=convertToNull

This should be in your local/db_connection_types.conf file (in my case under a mysql stanza.

Search using QuartzScheduler_Worker-32 in $SPLUNK_HOME/var/log/splunk/splunk_app_db_connect_server.log , as far as I know quartz scheduler worker number is same for all different steps for single DB input execution at particular time (NOTE: Same quartz scheduler number will assign to another jobs, it is starting from 1 and will go to 32 (Increment of one for every new job) and once it reach 32, it will reset again to 1 & this is my observation only)

Look through the _internal logs and see this doc: Troubleshooting DB Connect and see if that helps you finding the root caue.
