Bonita failed to start after update (ARJUNA)

Hello !

The context is an update from Bonita 7.7.4 to the latest version, with custom tomcat Bondle and tomcat v9.0.56.

I updated my Bonita install using bonita-migration-distrib-2.55.0 to Bonita 7.13 and updated my dirs (conf, webapp etc..).

For the update and configuration I used these ressources :

https://documentation.bonitasoft.com/bonita/2021.2/runtime/database-conf...

https://documentation.bonitasoft.com/bonita/2021.2/runtime/custom-deploy...

When Bonita starts I have these errors :

WARN: com.arjuna.ats.arjuna ARJUNA012073: BasicAction.End() - prepare phase of action-id 0:ffff7f000001:923a:61b39ba5:7b
failed.

Please tell me if you need the full stack or information about my configuration.

Also I see Bonita trying to connect to the databases in mysql using show full processlist command.

Could you help me ?

Thank you in advance !
