Goal

If an Solaris Cluster Resource Group Manger (RGM) method callback times out, the method's process group is killed by a SIGTERM signal. If the process tree does not exit within ten seconds, a SIGKILL is executed.

Starting with

• Solaris Cluster 3.2 / Solaris 5.10  and  <SunPatch 144221-05> or later
                                                         (<SunPatch 144220-05> for Solaris 5.9) or
• Solaris Cluster 3.3 / Solaris 5.10 and <SunPatch 145333-04> or later or
• Solaris Cluster 3.3u1 or later,

the default behavior for the RGM is that method core dumps are not generated when a method times out, however, system core dumps are generated when a node is rebooted by the RGM due to a resource's Failover_mode property being set to HARD and the resource method being stuck in the kernel and failing to exit after a SIGKILL.

Note: x86 patches are:

• 3.2 Solaris 10x86 :  <SunPatch 144222-05> or later
• 3.3 Solaris 10x86 :  <SunPatch 145334-05> or later
