* with bos.rte.libc at 6.1.9.300.

* applications have included IBM Tivoli Monitoring and
* Microsoft SCOM for AIX.

* RECOMMENDATION:
* Install APAR IJ04511.
* Prior to fix availability, an interim fix is available from
* either
* ftp://aix.software.ibm.com/aix/ifixes/ij04511/
* https://aix.software.ibm.com/aix/ifixes/ij04511/
* Installation of the ifix requires a reboot.
