Update: Bug 17628036 is fixed in Solaris 10 patch 15040-09 and Solaris 11.1 SRU16, both of which are now available on MOS. Customers with 15040-0 installed are recommended to install 15040-09. The Solaris 10 January CPU (Critical Patch Update) has been respun to included 15040-09 and is available from MOS:
https://updates.oracle.com/download/18074667.html (SPARC)The issue is far less common on Solaris 11, so you only need to update to SRU16 if you experience the issue. There will be a further "mop-up" fix in 15040-10 and a later SRU, but 15040-09 resolves the main issue and should be sufficient for most customers (addresses 95%+ of the instances reported).
Please note that there's an issue with revs -06 and -07 of the Solaris 10 Kernel patches 15040.
Please see Sun Alert 1619580.1 on MOS for further details. A number of Solaris 10 customers have hit the 2nd of the reported issues.
We've respun the Solaris 10 January CPU (Critical Patch Update) to revert to rev-05 (now available from MOS), we're expediting a fixed rev-09 (rev-08 won't be released), and have withdrawn revs -06 and -07 from release. Update: The Solaris 10 January CPU and Recommended patchset have been respun to include the fixed rev-09.
15040-09 will address Bug 17628036 and the current ETA for expedited release is Feb 21.
The Solaris 11 fix is also being expedited in Solaris 11.1 SRU16, but seems to be less prone to the issue.
I apologize for the inconvenience caused.
