15.1.2 Steps to take when an application cannot be executed (when the KFAA40005-E message is output)
If, when you attempt to execute an application, the KFAA40005-E message is output even though no other application or command is concurrently being executed, there might be a transaction that has not terminated and to which a locked resource remains allocated.
Execute the adbls -d cnct command to check the transaction processing status. Check the output item STATUS to determine whether there is any application or command for which STARTED is displayed.
If there is any application or command for which STARTED is displayed, either wait for the applicable transaction to terminate or use the adbcancel command to terminate the applicable transaction.
