S. O.S : You will not be able to edit the reconciliation information until

Hello
I can't do the reconciliation and this message shows up 

"Another user XXXX {sysadmin) has locked account 1060 XXXX  for reconciliation You will not be able to edit the reconciliation information until
XXXX (sysadmin) has finished working with this account. "

How Can I fix the problem, please
