#200219: Solaris 10 x86 Platform Patches 118345-05 or Later and 118565-03 or Later May Cause a System Hang

Solaris 10 x86 Platform Patches 118345-05 or Later and 118565-03 or Later May Cause a System Hang

Category :	Availability
Release Phase :	Resolved
Product :	Solaris 10 Operating System for x86 Platforms
Bug Id :	6356925
Date of Workaround Release :	09-JAN-2006
Date of Resolved Release :	01-Apr-2008

Changes were made to libc(3LIB) in patch 118345-05 and to libproc ... see below:

1. Impact

Changes were made to libc(3LIB) in patch 118345-05 and to libproc in patch 118565-03 such that both these patches must be installed together.

If the libproc patch is installed without installing the corresponding change to libc(3LIB) OR the libc(3LIB) patch is installed without the corresponding change to libproc, then the system may hang as soon as libproc is invoked.

An example of this is seen when running Explorer which will hang on the following command:

    prctl -n zone.cpu-shares -i zone global

2. Contributing Factors

This issue can occur in the following releases:

x86 Platform

Solaris 10 with patch 118345-05 (or later) or 121208-01 or 121208-02 AND without patch 118565-03 (or later)
Solaris 10 with patch 118565-03 AND without patch 118345-05 (or later) or patch 121208-01 (or later)

Note: Solaris 8, Solaris 9, and Solaris 10 on the SPARC platform are not impacted by this issue.

3. Symptoms

If the described issue occurs, the truss(1) of svsc will look similar to the following:
