Could not acquire a lock

Hello,

I'm trying to activate a smartform but I'm getting this error message:

Error Text of the Database: "[ASE Error SQL12205]Could not acquire a lock

within the specified wait period. SERVER level wait period=2400 seconds,

spid=259, lock type=exclusive row, dbid=4, objid=1260735642, pageno=5821264,

rowno=5. Aborting the transaction.#"

I´ve checked this notes:

1634716 - SYB: Lock timeout or deadlocks --> This is configured correctly

To prevent lock promotion, set the ASE configuration as follows:

'row lock promotion HWM',  2147483647

'row lock promotion LWM',  2147483646

           
1749935  - SYB: Configuration Guide for SAP ASE 15.7
           

What can I do?

Best Regards
