Oracle Solaris 11.2 kernel zones supports both backwards and forwards compatibility which means you can also run oracle Solaris 11.3(When it release) on the kernel zone where your global zone can still with oracle Solaris 11.2 In most of the Solaris 11 projects, they may have already deployed the traditional native zones(Whole root) and now may be they are thinking that how to convert the whole root zones as kernel zones. When error log messages indicate that a system event failed to be logged, generated, or posted.On Oracle Solaris 11.2, as we have already seen that kernel zones are completely isolated from the global zone. The system event framework checks this value every time a system event is generated by ddi_log_sysevent and sysevent_post_event.įor more information, see the ddi_log_sysevent(9F) and sysevent_post_event(3SYSEVENT) man pages. Once the size of the system event queue reaches this limit, no other system events are allowed on the queue. Maximum number of system events allowed to be queued and waiting for delivery to the syseventd daemon. This solution should be treated as no more than an interim workaround until the root cause is remedied. Among the side effects is a reduction in the number of threads that the kernel can create. The increased consumption means other resources that are competing for the same pool of memory will have the amount of space available to them reduced, possibly decreasing the system's ability to perform work. Increasing the default stack size means that almost every kernel thread will have a larger stack, resulting in increased kernel memory consumption for no good reason. The best solution for this problem is to determine why the system is running out of space and then make a correction. When the system panics because it has run out of stack space. The value of N is the default value of default_stksize. If these conditions are not met, the following message is displayed: Illegal stack size, Using N Also must be a multiple of the system page size. Must be greater than or equal to 8192 and less than or equal to 262,144 (256 x 1024). Affects threads created after the variable is changed. For more information, see the getpagesize(3C) man page. Unitsīytes in multiples of the value returned by the getpagesize parameter. Data Typeģ x PAGESIZE on SPARC systems with sun4u processorsĤ x PAGESIZE on SPARC systems with sun4v processors If default_stksize is set, it overrides lwp_default_stksize. No thread can be created with a stack size smaller than default_stksize. Specifies the default stack size of all threads. For ZFS-related memory parameters, see Oracle Solaris ZFS Tunable Parameters.
