Where to download sos.dll

This option can be very expensive, because it verifies whether all the objects in the finalizable queues are still rooted. The -short option limits the output to the address of each object. If it is used in conjunction with -allReady , it enumerates all objects that have a finalizer that are no longer rooted. If it is used independently, it lists all objects in the finalizable and "ready for finalization" queues.

Causes the debugger to break in the debuggee on the next collection of the specified generation. The effect is reset as soon as the break occurs. To break on the next collection, you have to reissue the command. At that time, the debuggee is in the right state for FindRoots to identify roots for objects from the current condemned generations.

Displays statistics about garbage collector handles in the process. The -perdomain option arranges the statistics by application domain. Use the GCHandles command to find memory leaks caused by garbage collector handle leaks. For example, a memory leak occurs when code retains a large array because a strong garbage collector handle still points to it, and the handle is discarded without freeing it. Searches memory for any references to strong and pinned garbage collector handles in the process and displays the results.

If a handle is found, the GCHandleLeaks command displays the address of the reference. If a handle is not found in memory, this command displays a notification. Displays data that indicates when registers or stack locations contain managed objects. If a garbage collection occurs, the collector must know the locations of references to objects so it can update them with new object pointer values. Displays information about references or roots to an object at the specified address.

The GCRoot command examines the entire managed heap and the handle table for handles within other objects and handles on the stack. Each stack is then searched for pointers to objects, and the finalizer queue is also searched. This command does not determine whether a stack root is valid or is discarded. Use the CLRStack and U commands to disassemble the frame that the local or argument value belongs to in order to determine if the stack root is still in use.

The -nostacks option restricts the search to garbage collector handles and reachable objects. Displays the location and size in the garbage collection heap of the argument passed in. When the argument lies in the managed heap but is not a valid object address, the size is displayed as 0 zero.

Displays all available commands when no parameter is specified, or displays detailed help information about the specified command. The faq parameter displays answers to frequently asked questions. Displays the generation sizes for each heap and the total free space in each generation on each heap.

If the - inclUnrooted option is specified, the report includes information about the managed objects from the garbage collection heap that is no longer rooted. Releases any resources used by the family of Hist commands. Generally, you do not have to explicitly call HistClear , because each HistInit cleans up the previous resources.

Examines all stress log relocation records and displays the chain of garbage collection relocations that may have led to the address passed in as an argument. Displays information related to both promotions and relocations of the specified root. The root value can be used to track the movement of an object through the garbage collections. Displays the objects preceding and following the specified address. The command looks for the address in the garbage collection heap that looks like a valid beginning of a managed object based on a valid method table and the object following the argument address.

Prevents running unsafe commands when using a minidump. Pass 0 to disable this feature or 1 to enable this feature. By default, the MinidumpMode value is set to 0. Minidumps created with the. Some commands may fail with unexpected errors because required areas of memory are not mapped or are only partially mapped.

This option protects you from running unsafe commands against minidumps. Displays the MethodTable structure and EEClass structure for the specified type or method in the specified module.

The specified module must be loaded in the process. To get the proper type name, browse the module by using the Ildasm. The module name parameter can also be the debugger's name for a module, such as mscorlib or image The type must be fully qualified.

Displays the size of the specified object. If you do not specify any parameters, the ObjSize command displays the size of all objects found on managed threads, displays all garbage collector handles in the process, and totals the size of any objects pointed to by those handles.

The ObjSize command includes the size of all child objects in addition to the parent. The -aggregate option can be used in conjunction with the -stat argument to get a detailed view of the types that are still rooted. By using! Displays and formats fields of any object derived from the Exception class at the specified address.

If you do not specify an address, the PrintException command displays the last exception thrown on the current thread. The -nested option displays details about nested exception objects. The -lines option displays source information, if available. ProcInfo [ -env ] [ -time ] [ -mem ]. Displays the list of runtime callable wrappers at the specified address that are awaiting cleanup. Causes the debugger to stop when the specified exception is thrown, but to continue running when other exceptions are thrown.

The -derived option catches the specified exception and every exception that derives from the specified exception. Displays the specified SyncBlock structure or all SyncBlock structures. If you do not pass any arguments, the SyncBlk command displays the SyncBlock structure corresponding to objects that are owned by a thread. A SyncBlock structure is a container for extra information that does not need to be created for every object.

It can hold COM interop data, hash codes, and locking information for thread-safe operations. Displays information about the managed thread pool, including the number of work requests in the queue, the number of completion port threads, and the number of timers.

Turns the specified metadata token in the specified module into a MethodTable structure or MethodDesc structure. You can also pass the debugger's name for a module, such as mscorlib or image DLL file you need to download sos. You can read more information about sos. DLL file and found it here on Fix4Dll. Thank you very much. I am so happy that I found you on Facebook. So much useful information! Download Sos. You are running: Unknown A suitable version of sos.

Unknown is not your OS? Asked 7 years, 4 months ago. Active 2 years, 7 months ago. Viewed 7k times. Improve this question. You can get the appropriate version of SOS. You should not replace the version on your machine. Just use. If you debug dumps frequently, I recommend keeping a repository of all unique versions of SOS that you come across.
