Solaris 10 Systems With Logical Domains Can Exhibit a Recursive Mutex Panic (Doc ID 1442042.1)

Last updated on AUGUST 21, 2018

Applies to:

Solaris Operating System - Version 10 3/05 to 10 1/13 U11 [Release 10.0]
Information in this document applies to any platform.


If the described issue occurs, the system will exhibit a panic. The top of the panic stack trace will be similar to the following:

Lower stack frames may differ.

A 'Recursive Mutex Panic' occurs when the thread that is holding the mutex tries to grab the same mutex again.
This could put the process in a loop and shouldn't happen. It results in a panic.
