Issue

• We have upgraded the to Fuse 6.3.0-262 from Fuse 6.1.0(R4 patch). We have not changed any configuration related to DB and application is working fine in production with 6.1.0.
• Upgraded Fuse is deployed to higher environment and working fine but intermittently we are getting DB connection issue.
• We have also checked the DB connections and all are in inactive state. after taking retsart of Worker, issue get resolved.
