Causes and What to Collect Items to Investigate Summary Related Information Introduction This document discusses MALLOCFAIL errors on native Cisco IOS, as well cisco memory leak as steps to take and information to gather before you open a Cisco Technical Assistance Center (TAC) case or reload the device in order to expedite problem resolution. This document is not exhaustive, but provides a general https://groups.google.com/d/topic/fds-smv/bhbWrXd2lK0 guideline used in order to troubleshoot memory issues with many routers and switches. MALLOCFAIL Errors Memory problems manifest themselves in several ways on switches and routers. In many instances, a device that experiences memory errors is reloaded before the appropriate data is gathered. Memory issues generally appear in the form of MALLOCFAIL errors in the logs of your router or switch. These errors are important because they provide "road signs" to direct the investigation. http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-151m-t/116467-technote-ios-00.html Here is a sample MALLOCFAIL error: %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failedfrom 0x60103098, alignment 0 Pool: Processor Free: 5453728 Cause: Memory fragmentation Alternate Pool: None Free: 0 Cause: No Alternate pool The first thing to notice is how much memory you need to allocate and how much free memory you have. This example shows a scenario where you must allocate 65KB from a pool that has only approximately 5.45MB free. The output indicates that, even though there is enough free memory, the largest contiguous block is smaller than 65KB, and the memory allocation failed. While, by definition, this is considered memory fragmentation, this is not usually the cause. Most often, it is simply caused by low memory in the pool itself. The second thing to notice is the pool type. The prevoius example dealt with the Processor pool. This is important because it is the first road sign that directs the investigation and what needs to be checked. The pool specified should be either Processor or I/O. Here is an example of an I/O memory error: %SYS-2-MALLOCFAIL: Memory allocation of 65548 bytes failed from 0x400B8564, alignment 32Pool: I/O Free: 39696 Cause: Not enough free memoryAlternate Pool: None Free: 0 Cause: No Alternate pool The next sections detail these pools further. Once the pool is identified, you can focus your efforts accord

I installed the vmware gsx 3.2.1 build-19281 version http://www.xml.com/ldd/chapter/book/ch02.html and everything worked fine. I made a new virtual machine and tried to run it. But it couldn't start. When i looked into the log file i found this error:Jan 16 memory allocation 21:59:58: vmx| \[msg.log.error.unrecoverable] VMware GSX Server unrecoverable error: (vmx)Jan 16 21:59:58: vmx| Unrecoverable memory allocation failure at F(5757):336My system has 756 mb ram and 1.4 gb swap space. I made a memtest but it didn't find any errors. I tried to change the amount of ram that the virtual machine allocates, i tried from 4 mb to 500 mb but it never sys-2-mallocfail memory allocation worked. Do you have any ideas what could be the problem?The whole log file here:Jan 16 21:59:57: vmx| Log for VMware GSX Server pid=8284 version=3.2.1 build=build-19281 option=BETAJan 16 21:59:57: vmx| Command line: "/usr/local/lib/vmware/bin-debug/vmware-vmx" "-C" "-@" """" "/var/lib/vmware/Virtual Machines/Windows 2000 Professional/Windows 2000 Professional.vmx"Jan 16 21:59:57: vmx| vmxvmdb: Index name being generated from config fileJan 16 21:59:57: vmx| VMXVmdbConnectServerd - Trying to discover serverdJan 16 21:59:57: vmx| ConfigDB: Set ConfigVersion to 7Jan 16 21:59:57: vmx| ConfigDB: Set HWVersion to 3Jan 16 21:59:57: vmx| MStat: Creating Stat system.cpuusageJan 16 21:59:57: vmx| MStat: Creating Stat system.ramJan 16 21:59:57: vmx| MStat: Creating Stat system.uptimeJan 16 21:59:57: vmx| MStat: Creating Stat system.loadJan 16 21:59:57: vmx| pcpu #0 CPUID numEntries=1 AuthenticAMDJan 16 21:59:57: vmx| pcpu #0 CPUID version=0x662 features=0x383fbff extFeatures=0x0 ebx=0x0Jan 16 21:59:57: vmx| CPUID common features: 0x383fbff extFeatures: 0Jan 16 21:59:57: vmx| AllocTrack: Successfully initialized, pass-through mode, log level 0, log stack crawl FALSE.Jan 16 21:59:57: vmx| AllocTrack: Options changed globally, now log level 1, log stack crawl FALSE.Jan 16 21:59:57: vmx| changing directory to /var/lib/vmware/Virtual Machines/Windows 2000 Professional/.Jan 16 21:59:57: vmx| Config file: /var/lib/vmware/Virtual Machines/Windows 2000 Professional/Windows 2000 Professional.vmxJan 1
Compiling and Loading The Kernel Symbol Table Initialization and Shutdown Using Resources Automatic and Manual Configuration Doing It in User Space Backward Compatibility Quick Reference It's high time now to begin programming. This chapter introduces all the essential concepts about modules and kernel programming. In these few pages, we build and run a complete module. Developing such expertise is an essential foundation for any kind of modularized driver. To avoid throwing in too many concepts at once, this chapter talks only about modules, without referring to any specific device class. All the kernel items (functions, variables, header files, and macros) that are introduced here are described in a reference section at the end of the chapter. For the impatient reader, the following code is a complete "Hello, World" module (which does nothing in particular). This code will compile and run under Linux kernel versions 2.0 through 2.4.[4] [4]This example, and all the others presented in this book, is available on the O'Reilly FTP site, as explained in Chapter 1, "An Introduction to Device Drivers". #define MODULE #include
