To use 16GB of memory you will need XEON processor and a quantity of (4) 4GB sticks that are dual ranked and use a x8 data width (2Rx8).


No, there is no way that Windows can guess what RAM is supported. You need to consult the hardware documentation of your server for that


You've already discovered that there's two sets of RAM on the 6500/7600 series supervisors - the switch processor or supervisor RAM, and the MSFC or "route processor" RAM. The terminology isn't helped by there being three different names for each of these two components. The "sh ver" output is for the MSFC (RP) (add the two values together). "remote command ...


I can see the issue here - if you look on the compatibility tab of THIS link you'll see it's not a supported configuration. Presumably because it's 12800 memory rather than the 1066 or 1333 memory HP sell but it could be another factor - either way next time be more careful selecting products, if in doubt always buy from the vendor for this exact reason.


Hmm, that's Kingston RAM. Are you absolutely sure it is compatible? (I advocate using HP RAM in HP servers) What was the old RAM configuration? I'd suggest going back to the old configuration... To start, please remove power (and power cables) from the system for a few minutes. Plug them back in and try again. Also, is your ILO3 configured? You can use ...


this may be a little bit late, but I can say that blaming the OS is simply not the way to go. the OS is designed to meet the expectations of several different use case scenarios, therefore, you MUST configure it to meet your requirements. not only this, but if you are having so much load that the system is crashing, then you have to optimize your system, or ...


Server 2012R2 as the host would actually allow you to start all your VMs simultaneously, even if their total RAM exceeded that of the host. They'll have some of their state paged to disk until the Dynamic Memory agent kicks in and balloons out the unneeded memory. As for your question about IIS, I don't know how it's coded. It could obviously be coded ...


With PHP 5.3.3 on CentOS 6.3 this was an error I ran across because the webserver user didn't have a valid shell. Adding .bashrc to the nginx user's home directory fixed it for us. See answer as this dupe question: https://stackoverflow.com/questions/20648949/php-warning-exec-unable-to-fork/24517481#24517481


You need 3rd party software to do this. One program that can do this is ImDisk. ImDisk will create a new drive letter which you can make a link to from any folder you want: mklink /D C:\somePath E:\somePath.


When did this server show 16GB of RAM and when did it show 8GB of RAM? I'm assuming this is not a new installation because you're using a kernel that's over 1 year old. Can you run updates? My general recommendation would be to update your system's kernel (and OS), since that's just the right thing to do, and you're on the base kernel of CentOS 6.4... ...


A similar problem happened when I installed new DIMMs in my PowerEdge R815. I thought one of the DIMMs was bad, but didn't know which of the 32 DIMMs it might be. It turned out that the hardware's LCD panel (and the hardware log) reported the failure, and provided the DIMM slot id. When I reseated the DIMM, the error went away -- so it wasn't an error that ...


The memory should be freed when a program exits (regardless if the program freed it or not). For example. [kbrandt@ny-kbrandt01: ~] cat eat_mem.c #include <stdlib.h> #include <string.h> #include <unistd.h> int main() { #1 GByte const int m = 1024*1024*1024; #Allocate a gig void *p = (int*)malloc(m); #Write a Gigs worth ...


You can find the documentation in man 5 proc: This file contains the kernel virtual memory accounting mode. Values are: 0: heuristic overcommit (this is the default) 1: always overcommit, never check 2: always check, never overcommit In mode 0, calls of mmap(2) with MAP_NORESERVE are not checked, and the default check is very weak, leading to ...


At first I recommends you to enable vSwap memory model because it's simpler and more reliable than old UBC styled system. With it you can replace this vzctl set 101 --physpages 0:2G --swappages 0:2G --kmemsize unlimited --privvmpages 2000M:2G --vmguarpages 2000M:2G --oomguarpages 2G --save by vzctl set 101 --physpages 2G --swappages 2G --save After this ...


I would guess your problem is actually too many Apache clients for your server's memory. When you get a large surge in traffic the Apache processes build up eventually using up all the RAM . This forces the OS to begin forcibly swapping processes in and out which tends to make things much worse. Eventually your swap memory runs out and the OS kills whatever ...


frankly speaking you are only getting 1 GB which vps promises and the other 1 GB 'burstable' it is part of shared pool , it will happen only when First 1 GB is fully utilized & Shared Memory pool has memory available for your VPS to use than only burst thing works, which means no guaranty. As far as question whether 1 GB dedicated is available, it ...


Just an idea, might not be OS memory, but might be a limit in PHP on memory use. Look in your php.ini file for the parameter memory_limit. If it's not defined, it might be defaulting to 8M, 32M, or 128M depending on which PHP version you're on. http://php.net/manual/en/ini.core.php#ini.memory-limit
