Solution Type Sun Alert Sure Solution 1019357.1 : Sun Fire Server with Solaris 10 may Panic or Reset with lpost message, asynchronous event, fail to stop CPU or send_mondo timeout
PreviouslyPublishedAs 238746 Bug Id <SUNBUG: 6684726>, <SUNBUG: 6699498> Date of Preliminary Release 12-Jun-2008 Date of Resolved Release 01-Aug-2008 Sun Fire Server with Solaris 10 may Panic or Reset with lpost message, asynchronous event, fail to stop CPU or send_mondo timeout. (see below for full details) 1. ImpactLoss of application availability may occur due to a system panic or reset. This type of fault is typically diagnosed to be a hardware failure and may lead to unnecessary hardware replacement.2. Contributing FactorsThis issue may occur on the following releases and platforms:SPARC Platform
This issue is specific to the Midrange servers listed above and only seen with SPARC USIV+ 1.5GHz and 1.8GHz CPUs. It is considered possible to occur with USIV+ 1.95 GHz CPU. Current firmware versions of System Controller (ScApp) ScApp:5.20.9 (as delivered in patch 114527-10) and earlier are affected. It has been observed when running programs that access OBP from the OS. Examples of programs that access OBP from the OS are prtdiag, prtconf, cfgadm, picl, or other third party System management software. This issue is very timing dependent and expected to be rare. 3. SymptomsConsole logs and core files are useful in identifying whether the system is experiencingthis issue. ------------------------------------------- Console Logs Showing send_mondo panic: domainA console login: {/N0/SB2/P0/C1} @(#) lpost 5.20.8 2007/11/20 10:33 {/N0/SB2/P0/C1} Copyright 2007 Sun Microsystems, Inc.

WF 12-Jun-2008: karen, releasing Internal Resolution Patches 114527-11, 137111-04 Internal Comments Please send technical questions to the following email: sunalert-tech-questions@sun.com and CC the following persons: Internal Contributor/Submitter Internal Eng Responsible Engineer Internal Services Knowledge Engineer The fix will require a firmware upgrade to System Controller Application (ScApp) 5.20.10 in patch 114527-11 and the Solaris 10 kernel patch. As a workaround the command seen in the core file that caused the failure at a customer's site should be disabled to prevent repeat failures. This timing issue is load dependent, and a machine that has seen the issue has a higher potential for seeing the issue again. It is not recommended to proactively disable all commands in the Contributing Factors section, since the application mix required to initiate the failure is rare.
