ORA-04020: deadlock detected while trying to lock object - Oracle Package

I have an Oracle Package (Schema1) that is calling another Oracle Package (Schema2) over a DB link. There are no recent code changes. When I try to compile the package in (Schema1) it throws the following errors. (replaced the actual schema names with 1 and 2 for clarity) > ORA-04052: error occurred when looking up remote object > SCHEMA2.PKG_NAMEHERE@SCHEMA2.LINKNAME.INT@SCHEMA1 > > ORA-04020: deadlock detected while trying to lock object > SCHEMA2.PKG_NAMEHERE@SCHEMA2.LINKNAME.INT@SCHEMA1 What we have tried 1. Killed all user sessions 2. Recompiled the package in SCHEMA2 even so SCHEMA1 that calls it over the DBLINK failes with "ORA-04020: deadlock detected" We have 4 Database regions, and this is only happening in two of the regions. **Notes:** SCHEMA1: Oracle 11g SCHEMA2: Oracle 12c (on ExaData)
