"plugin shutdown" errors in vault audit logs

Hi

I have deployed a custom database plugin and occasionally seeing the below responses in Vault audit logs when users read on a database role.

1 error occurred:
	* plugin shutdown

The error goes away upon retry.

DEBUG logs shows the following

2020-06-29T00:00:27.510Z [DEBUG] secrets.database.database_e41bf3c6.artifactory-database-plugin: plugin process exited: path=/vault/plugins/vault-plugin-database-artifactory pid=941 error="signal: hangup"
2020-06-29T00:00:27.511Z [DEBUG] secrets.database.database_e41bf3c6.artifactory-database-plugin: plugin process exited: path=/vault/plugins/vault-plugin-database-artifactory pid=909 error="signal: hangup"

Any suggestions on how to debug this further?

vault version: 1.4.3
Deployed as container on a host using the official open source docker image.

Thanks in advance for any help.
