i am trying to run a query that uses dblink.
the wquery works fine at times and execution time is also quick but some time i get the following errors

[1]: (Error): ORA-12801: error signaled in parallel query server P008, instance abcet:SQUAD5(5) ORA-00600: internal error code, arguments: [ktsxaffs1], [], [], [], [], [], [], [] ORA-02063: preceding 2 lines from SQUAD

any solution to this.

Thanks in advance
