ORA-00600: internal error code, arguments: [17059], [], [],

=========================
General
=========================
Oracle version is 11.1.x
In alert.log there are constantly, every minute these error messages:
ORA-00600: internal error code, arguments: [17059],[],[]

For each error message a trc file is generated, until system is 100% full.

=========================
Solution
=========================
The issue is related to Oracle bug, resolved in 11.2.x.
The problem is with SQL statement(s) having too many child.
The solution is to flush the shared pool:

ALTER SYSTEM FLUSH SHARED_POOL;

After the shared pool was flushed, trc files stopped to be generated.
