Process using up system memory

I'm running 10.6.3 on a Late 2008 Aluminum Macbook. Lately I've been experiencing an issue with a process called "fldirpatcher" using up system memory for about one minute after bringing the device out of sleep. Has anyone else experienced this or know what this process is?

Backupd process using too much memory, blocking up system (Yosemite)

Hello,
Since I upgraded to Yosemite (maybe even only after I installed 10.10.1) on my Early 2009 17" MacBook Pro, after a while, a process called "backupd" is started, using all available memory, then switching to virtual memory. After a few hours, it can take more than 20 GB of virtual memory, making the MacBook Pro very slow and unresponsive. Killing the process using Activity Monitor (which can take many minutes because of the unresponsiveness) regains the used memory, and almost immediately makes the machine responsive again.
What is this "backupd" doing anyway, are there means to prevent it from running at all or to let it stop using so much memory, or might there be a bug in OS X 10.10.1?
Cheers,
Dirk

I did that anyway yesterday, to turn off the mobile backups, as my MBP is not so mobile anymore
Let's see if it works and if the problem is solved by it

RAC node process using 25% physical memory

We have a QA server is non-RAC, and production is two-node RAC. We have a migration app that does an INSERT from SELECT over 2 instances. All of the machines have been in successful day-to-day use for several months...our only troublespot seems to be the migration app.
Today we started the app on the QA server and watched the oracle processes using top. They ran normally and finished without any problems.
The same app started on either of the RAC nodes produced process memory errors and died.
As the app ran, there was a process reading the data from the source instance and a process writing to the target instance. We confirmed this by querying the session data. It doesn't matter which of the nodes runs which target process...the result is the same.
The reading process(session) on the source instance seems to run normally. The write process on the target instance, however, begins slowly accumulating memory in about 16M chunks and holds on to them.
We saw this in the RES and in the MEM columns of top. The target process never released any memory, but slowly grabbed it until its
RES was 4GB and the %MEM was about 30%. The app then died with process memory error. This is reproducible over several runs.
( Per Metalink Note 567506.1, the recommended value for Linux 64-bit is 4294967295 ..we have that set. )
There are other oracle processes and instances running on both nodes which do not seem to be affected. The total number of processes on each machine is around 750..much lower than the nprocs ulimit of 63K.
These process are both oracle sessions spawned by the app.
I haven't seen any info on the web or Metalink that matches these symptoms, so I thought I'd try the experts.
Why would the write session continuously use up physical memory, but only on RAC nodes?
We are running RHEL5 on Dell Poweredge 2950 w 16K Physical mem. Version of 10g is R2.0.4.

We saw this in the RES and in the MEM columns of top. The target process never released any memory, but slowly grabbed it until its
RES was 4GB and the %MEM was about 30%. How does the writer process work? Does it use PL/SQL? Does it use bulk processing? How does it call the reader process? Or does the reader process call it? Is this over a database link.
The app then died with process memory error. This is reproducible over several runs.If this is an Oracle server process, then there should be an entry in the alert log of the instance that recorded the crash and includes the name of the trace file generated by the crash.

The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.

I encountered this problem on our SQL2012 and I have tried different scenarios (see below) to no avail. I have decided to give up and check if someone here has encountered this and resolved it.
One thing I know, it's not a memory issue. Both servers we're using has lots of memory to spare and we monitor the memory as the replication goes through it's steps.
I hope someone can help me on this. Thanks!
The Error:
The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.
Our Scenario
We're using SQL Server 2012 SP1. All subscriptions are pull based.
We're using direct Merge Replication (not FTP or web sync)
We already have 10 active replications with larger databases. Only 1 has this issue.
Database size is less than 5 GB
Rebuilding the publisher is not an option.
What have I tried?
There is no memory problem --- we have lots to spare
I have tried re-initialization of the database. Same problem.
I tried deleting the database and reinitializing it. Same problem
New snapshot. Same problem.
I tried changing the subscriber server but still same issue.
MCP, MCSD, MCDBA (ANXA)

Here is the result for the sp_configure on our subscriber. We're doing a pull on the server with the issue.
name
minimum
maximum
config_value
run_value
max server memory (MB)
128
2147483647
2147483647
2147483647
In addition, I made a comparison between the working servers and the one with the issue -- there seems to be a difference in the service pack. Publisher has none but the subscriber is operating on SP1. But still strange as only 1 database is affected.

How can one use the physical memory of our system rather than virtual memory while running Labview?

We have a Windows NT system with 2 Gb of physical memory and would like to utilize the RAM fully using Labview. What usually occurs is that Labview uses a tremendous amount of page file space while a majority of the physical memory is unused. Is there a way to configure Labview (or our system) to overcome this problem? It seems that our processes would be much faster if they were mainly using the physical memory. Is it possible to trick the system, by creating a RAM disk and allocating this as virtual memory space?

LabVIEW the application doesn't know anything about physical versus
virtual memory. LV asks the OS for general purpose memory and goes
from there.
Drivers like DAQ and IMAQ will have a combination of general user
memory and page lo
cked physical buffers.
I'm not up on the details, but this is something that the OS is in
control of, so that is where you need to look for the solution. One
of the things to look at is the disk cache. By default, I think that
NT takes a percentage of the RAM to use for disk cache. With that
much RAM, this is probably unnecessary and is using too much.
Similarly, the OS may be attempting to keep the working set size
to a fraction of the total RAM to reserve space for other things.
It doesn't make sense to me, but then I don't work for MS.

ITunes 7.6 uses massive amounts of system memory

When playing music in iTunes 7.6 on cover flow view, I notice from watching the processes tap of Windows Task Manager, that iTunes uses about 70MB of RAM when initially opened but that with each unique album cover it displays (by clicking on different songs from the library), the memory usage increases in increments of anywhere between 4MB and 40 MB. I first noticed the problem when my synchronization program displayed an error message stating that my computer was out of virtual memory. When I looked at the processes tab of Windows Task Manager, iTunes was using over 1GB of system memory (I have 2GB). Any ideas? Thanks!

not only does it hord your memroy.... it loads down your processor as well.
someoneelse mentioned it was trying to convert video files (constantly and never stops trying), and removing the video files should help...it did help, a little... 7.6 still lags and is slowest program I have installed on my PC at the moment.

Why are the following processes always using lots of memory?

Can someone tell me why the following processes are always using lots of memory and are always running?
kernel_task 280MB
java 300MB
clamd 120MB
mds 100MB
WindowServer 100MB
coreservicesd 60MB

Because they require that much memory and because the processes are always in use.
This is one reason why the minimum system memory requirement is 1 GB.
Now, you have one third-party process listed, clamd, which is used by ClamXAV anti-virus software. If you can uninstall it you will recover the memory needed by clamd.

Can I get a List of all the running processes in the system using java ?

I want a complete list of all the Running processes currently in the system.
List of running processes is like, in MS Window environment while we presses ctrl + alt + del and we get a small window containing a list of all the running processes currently in system.
I hope somebody have done the same and will help me.
thanx.

Here is the sample code to get All running process in your system .
Its in C++.And you have use JNI to use this code.

Strange memory behaviour using the System.Collections.Hashtable in object reference

Dear all,
Recently I came across a strange memory behaviour when comparing the system.collections.hashtable versus de scripting.dictionary object and thought to analyse it a bit in depth. First I thought I incorrectly destroyed references to the class and
child classes but even when properly destroying them (and even implemented a "SafeObject" with deallocate method) I kept seeing strange memory behaviour.
Hope this will help others when facing strange memory usage BUT I dont have a solution to the problem (yet) suggestions are welcome.
Setting:
I have a parent class that stores data in child classes through the use of a dictionary object. I want to store many differenct items in memory and fetching or alteging them must be as efficient as possible using the dictionary ability of retrieving key
/ value pairs. When the child class (which I store in the dictionary as value) contains another dictionary object memory handeling is as expected where all used memory is release upon the objects leaving scope (or destroyed via code). When I use a system.collection.hashtable
no memory is released at all though apears to have some internal flag that marks it as useable for another system.collection.hashtable object.
I created a small test snippet of code to test this behaviour with (running excel from the Office Plus 2010 version) The snippet contains a module to instantiate the parent class and child classes that will contain the data. One sub will test the Hash functionality
and the other sub will test the dictionary functionality.

Hi Cor,
Thank you for going through my post and took the time to reply :) Most apreciated. The issue I am facing is that the memory is not reallocated when using mixed object types and is not behaving the same. I not understand that .net versus the older methods
use memory allocation differently and perhaps using the .net dictionary object (in stead of the scripting.dictionary) may lead to similar behaviour. {Curious to find that out -> put to the to do list of interesting thingies to explore}
I agree that allocated memory is not a bad thing as the blocks are already assigned to the program and therefore should be reallocated with more performance. However the dictionary object versus hashtable perform almost identical (and sometimes even favor
the dictionary object)
The hashtable is clearly the winner when dealing with small sets of data.
The issue arises when I am using the hash table in conjunction with another type, for example a dictionary, I see that the dictionary object's memory is stacked on top of the claimed memory space of the hashtable. It appears that .net memory allocation and
reuse is for .net references only. :) (Or so it seems)
In another example I got with the similar setup, I see that the total used memory is never released or reclaimed and leakage of around 20% allocated memory remains to eventually crash the system with the out of memory message. (This is when another class
calls the parent class that instantiates the child class but thats not the point of the question at hand)
This leakage drove me to investigate and create the example of this post in the first place. For the solution with the class -> parent class -> child class memory leak I switched all to dictionaries and no leakage occurs anymore but nevertheless thought
it may be good to share / ask if anyone else knows more :D (Never to old to learn something new)

How to find memory taken by a process using top command

I wanted to know how to find the memory taken by a process using top command. The output of the top command is as follows as an example:
Mem: 13333364k total, 13238904k used, 94460k free, 623640k buffers
Swap: 25165816k total, 112k used, 25165704k free, 4572904k cached

I hope, my question is clear as to how to find the memory taken by a process using top command.
Please revert with the reply to my query.

Have you tried "man top" to see the documentation for the top command?
How about the following: http://lmgtfy.com/?q=show+memory+with+top+command
The 5th column (VIRT) shows the amount of RAM + swap
The 6th column (RES) shows RAM
The 7th column (SHR) shows memory shared between processes

How to find memory taken by Oracle processes using top command

I wanted to know how to find the memory taken by Oracle processes using top command. The output of the top command is as follows as an example:

The different Oracle processes could be Oracle database, Oracle listener, Oracle enterprise manager etc.
I hope, my question is clear as to how to find the memory taken by a process using top command.

a short and correct answer would be: you can't.
As oracle uses a fair amount of shared memory, and that shared memory is attached to most of the oracle processes, the same memory appears a number of times.
you should rephrase your question / what is it you want to achieve?
you can ask oracle how much memory is assigned to it, v$sga, v$sgastat, v$process (for PGA). moreover, you as DBA are the one who configured that.
you can look at major an minor faults per process to see what is causing the paging (if you have any).
you can also look at the /proc/pid/statm pseudofilesystem for your oracle pids.

Can I use LabVIEW to load data directly into system memory? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Win32 function to read the data from the card and now I want it to go directly to system memory.

Can I use LabVIEW to load data directly into system memory from a VI? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Call Library function to read the data from the card and now I want it to go directly to system memory.
The data is being received at 1Mbps.
Thanks

Two questions:
One, if it's a serial card, then presumably it gives you more serial ports, like COM3, COM4, etc. If so, VISA would see the COM ports, and not the card directly. The drivers for the card should make it so that you see the extra serial ports from the OS. If you don't see the extra COM ports from VISA, then it sounds like the drivers for the card are not installed properly. Do the extra COM ports show up in Device Manager?
Two, you said that you're using a Call Library function to get the data and you want to put it into system memory. Errr.... you just read the data and you have it in memory by definition. Are you saying you need a way to parse the data so it shows up on a graph or something?

Why can't I use the 16GB DDR3 System Memory (2 Dimm) with 24GB flash Hard Drive Acceleration Cache?

I tried to customize the Envy 15t but I can't proceed on upgrading the following.
Error
24GB SSD Acceleration Cache requires purchase only up to 8GB System Memory.
Why can't I use the 16GB DDR3 System Memory (2 Dimm) with 24GB flash Hard Drive Acceleration Cache?
Can HP explain this to me? or any one? please

Hi,
The 24Gb cache drive will store manything and normally it will need at least twice the size (capacity) of RAM. Double 16Gb is 32Gb therefore 24Gb is not big enough.
Regards.

"airport" process uses all of the memory an cpu

After I reinstalled my MacBook and updated to the latest version of Tiger (10.4.8) my airport network behaves very strange. When I boot my MacBook or disconnect/connect my Airport network a process called "airport" is consuming all the CPU and memory. It uses one core exclusivly and gows to 1,2 GByte of RAM (even more virtual Memory). This slows down the macbook to almost still and heats up the CPU.
The only thing I can do is to kill the process. Then everything works fine. But this is annoying.
It seems to make no difference if I use a wireless LAN or not. When airport is enabled then this bug occurs.

On this thread,
http://discussions.apple.com/thread.jspa?messageID=349
2852, people that have Check Point Software's
SecureClient are reporting the airport process using
~95% of CPU time.
I had SecureClient installed and I can confirm that
if you uninstall SecureClient, the airport process
works normally again. I don't know if this is the
only source of this problem, but if you happen to
have SecureClient, then you might want to uninstall
and confirm if this solves your problem.
Also I would be curious if anyone is having this
problem that has never had SecureClient, or any 3rd
party VPN software.
I can confirm that at least some of my problem with the "airport" process was related to VPN software. After uninstalling the Cisco VPN client, problems dramatically reduced. Interestingly, I still have the Checkpoint client installed, but only rarely see problems with "airport".
