How To Fix ICC_TR180 - System error occurred during lock management

SAP Error Message - Details

• Message type: E = Error

• Message class: ICC_TR - Turkey

• Message number: 180

• Message text: System error occurred during lock management

What causes this issue?

An error occurred in the lock management system while the system tried
to lock an object when calling an ENQUEUE function module.

System Response

The system cannot enter the requested lock in the lock table
administrated by the ENQUEUE server, so the function module reports an
error. If the application program cannot deal with the problem, the
system automatically terminates the transaction.

How to fix this error?

The most likely cause of this problem is that the system cannot access
the ENQUEUE server. Either the ENQUEUE server or the message server
(which links the application server and the ENQUEUE server) is not
running.
Another possible cause is that when the system tried to enter the lock
in the lock table, the table ran out of space. If so, change the size
of the profile parameter enqueue/table_size, which controls how many
kilobytes are available for the lock table.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
