When I run an analyze on one of our schemas , code below:
BEGIN DBMS_STATS.gather_schema_stats (ownname => 'ISSLIVE', cascade =>true,estimate_percent => dbms_stats.auto_sample_size); END;

*
ERROR at line 1:
ORA-00054: resource busy and acquire with NOWAIT specified


This job is scheduled to run at 1am and does not coincide with another job. Any reason why I keep getting this? The same code runs without errors in other databases.

Any suggestions please.
