This is useful if you have a large crash dump file and want to create a smaller one.You can control what type of dump file will be produced:You cannot specify which process is dumped. How do I see the current process ? For Zimbra purposes, this technique is valuable when trying to identifiy and solve problems with the Zimbra Connector for Outlook. When trying to debug a process which may be behaving erratically or seemingly deadlocked (hung), it might be worthwhile creating a core dump from the process which is still running. If Process is omitted in any version of Windows, the debugger displays data only about the current system process.
The easiest way to do this is using WinDbg. This information is listed in the third line of output after the thread header. The following options are available in kernel mode.For a description of kernel-mode dump files and an explanation of their use, see This command can be used in a variety of situations:During live user-mode debugging, this command directs the target application to generate a dump file, but the target application does not terminate.During live kernel-mode debugging, this command directs the target computer to generate a dump file, but the target computer does not crash.During crash dump debugging, this command creates a new crash dump file from the old one.
I introduce here some commonly used methods of how to dump a process. Let's use the same logic we did previously to learn what is the next process seen by the Kernel after the "System" process. In the final entry in the preceding example, the owner is spoolss.exe. From above we see the first process is "System". The !process extension displays information about the specified process, or about all processes, including the EPROCESS block.This extension can be used only during kernel-mode debugging.For information about processes in kernel mode, see The following table describes some of the elements of the The eight-character hexadecimal number after the word PROCESS is the address of the EPROCESS block. All running processes will be dumped.The following example will create a user-mode minidump, containing full memory and handle information: How to dump user process. When in user mode, we usually attach to a particular process or the dump generated in user mode is of one process. In user mode, /m can be followed with additional MiniOptions specifying extra data that is to be included in the dump. If the value for KernelTime is exceptionally high, it might identify a process that is depleting system resources. WinDbg : .process The .process (dot process) command is used to switch the debugger into the context of the process. Dump details of all allocations in all heaps in the process Who allocated memory - who called HeapAlloc? A. If Process is 0 and ImageName is omitt…
In the final entry in the preceding example, the process address is 0x809258E0.The hexadecimal number after the word Cid.
/s **** SessionSpecifies the session that owns the desired process./m **** ModuleSpecifies the module that owns the desired process. There are many ways to dump the user process.
An exceptionally large working set size can be a sign of a process that is leaking memory or depleting system resources.Lists the paged and nonpaged pool used by the process. Using ADPLUS ADPLUS is the tool that Microsoft CSS often uses to take a dump. Subject: [windbg] Current Process I have here a "complete memory dump" and it looks like the BSOD was caused by a user mode call into the kernel. We also see for it's "ActiveProcessLinks.Flink" that is the next process, it is at "0xffff998b`c636b328" while the "ActiveProcessLinks.Blink" is at "0xfffff800`625ad3b0".
Units are the same as those of ElapsedTime.Lists the current, minimum and maximum working set size for the process, in pages. In the first entry, the owner is the operating system itself.The hexadecimal number after the word ObjectTable. In the final entry in the preceding example, the PEB is located at address 0x7FFDE000.The hexadecimal number after the word ParentCid is the PID of the parent process. In this example, the thread has a lock on one resource, a SynchronizationEvent with an address of 80144fc0. /m[MiniOptions] Creates a small memory dump (in kernel mode) or a minidump (in user mode) For more information, see User-Mode Dump Files.If neither /f nor /m is specified, /m is the default.. If the value for UserTime is exceptionally high, it might identify a process that is depleting system resources. There are 2 dump modes in this tool - one for hang and the other for crash dump.
By comparing this address to the list of locks shown by the This includes both paged in and paged out memory.In addition to the process list information, the thread information contains a list of the resources on which the thread has locks.
How do I list the loaded modules for that process ?
