High Memory in Cisco IOS upto 122-55.SE9.bin

Hi,
We have Cisco 2960TCL switches in our environment which have 64MB DRAM and 32MB default memories. When we are going to upgrade their IOS on
122-55-XX or upper builds then switch utilized 65% of its memory but when we installed IOS on 122-53-XX or lower builds switch utilize 33% - 35 % of their memory.
I do not think its bug type of issue.
Kindly advice me on this.
BR,
Arshad

Hi,
This can be expected since the newer versions will have more features and the *Init* process holding memory has gone up on some of them.
Hope this helps.

IOS IPS ver 5 and high memory usage

Hi,
Is anyone else having high memory issues when using ver 5? I have installed on a 1801 with 128 M memory. It only has 4 M free now. Is there a way to reduce the active signatures? I have disbaled some but the number of active is still at 338.
Thanks,
Scott

This issue usually occurs because of a memory leak. However it cannot be said that it is due to the IPS service running whcih is causing this problem. Following links may help you

SA520W - High memory usage, possible fix in 2.2.0 firmware?

As suggested by Thomas Watts, I'm starting a new thread to discuss the new SA520W firmware (2.2.0) and a possible resolution to high memory usage I'm experiencing on my network.
My current setup is: 16Mbit DSL > SA520W > SA300-10, all with stock settings (no fancy VLAN's etc.)
I have 4 CentOS 5/6 servers and a Windows 7 Ultimate station connected to the switch. I use CIFS to connect from Windows station to the other Linux servers and send large files. I currently notice the following behavior:
When the file transfer starts, the Intel 1Gbit NIC is nearly saturated, hitting 115MB/sec. After few seconds, the data transfer comes to a halt and the transfer speed drops to around 50MB/sec. If I check the memory usage before the file transfer, it is approximately to 50-60% (on a fresh router reboot). Every time I send large files to other machines, the router memory consumption increases and it does not lower after a reasonable delay. I end-up with high memory near 90% and the only solution I have is to reboot the router in order to bring it back to 50%.
Now, Thomas told me that this is simply a cosmetic issue, the memory is not actually 90% used. Yet, when the memory hits this threshold, I'm not capable to send files are normal LAN speeds I'm used to. Rebooting the router allows me to send only ONCE (and for few seconds) data at the expected LAN speeds.
I would apreciate any input from Cisco engineers as well other users who experience the same issue. I would also like to know if any related work was done into 2.2.0 firmware and when we expect to have it released to users.

Floren Munteanu

Hi Tom,
See below the answers.
Are you currently running the 2.1.71 code?
Yes
Are you using IPS?
No, the LAN is for internal use (no external users allowed)
Are you using Protectlink services?
No
Hardware wise, I did not changed anything on machines. All boxes have dual Intel EXPI9301CT NIC's (LACP was planned) but I currently use single connections for sanity reasons (disks won't allow greater speeds anyway). Previous to Cisco, I used a Netgear ProSafe router + switch which did not encountered the issues I mention. Honestly, at first I thought I'm dealing with some stupid disk issues on Windows. So I ran a quick test and the stats are proper:

As I mentioned before, everything is pretty much stock on router/switch settings. If you have any tips that allow me to identify the cause, I would appreciate the input. What puzzles me is the speed drop and quick memory usage increase. It occurs 7-10 seconds after the transfers begins. It looks like the data transfer hangs for a very short period of time (less than half of second) and the transfer speed decreases from 110-115MB/sec to 50-60MB/sec. The transfer is completed at this speed. No matter how many other files I try to transfer after, the speed won't go higher than 60MB/sec. If I reboot the router, I get the same cycle.

CiscoWorks LMS 4.0.1 High Memory Utilization on Windows 2K8 R2

Hi,
What causes LMS 4.1 to have high memory utilization?

I made a little batch
https://supportforums.cisco.com/docs/DOC-21031
It show what process in LMS is eating you RAM / Hogging the CPU.
I don't think resources are used very effectivly in LMS
I did have the impression that some virtual machines running LMS 3.2 actually performed better than real machines, as if the VMware saw it load all these java virtual machines and that it was 45 times the same thing only being used for a few % and therefore could be swapped to disk, leaving the resources to what was actually working in LMS.
What worries me more than the resources used is the gui per.formance.
Cheers,
Michel

Why does my iPod keep on crashing when I run high memory apps?

Why does my iPod keep on crashing when I run high memory apps? I have a 32 gb 4th gen iPod Touch with only 11gb used, and I currently run 6.1.5 Everytime I run a high memory app, without fail it crashes. These apps include but are not limited to instagram, infinity blade, subway surfer, gmail, clear vision 3, dropbox, and even Safari has crashed on multiple occasions. I tried resetting the settings and that seemed to work for about a day but now I'm back at square one.

Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync/delete all music and resync
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Can I upgrade FWSM 4.0.3 to 4.0.17 with Chassis IOS s72033-adventerprisek9_wan-mz.122-33.SXH4.bin ?

Hi,
Can I upgrade FWSM 4.0.3 to 4.0.17 with Chassis IOS s72033-adventerprisek9_wan-mz.122-33.SXH4.bin ?
In chassis's slot we have ACE and FWSM slot also. if I will upgrade chassis it will reboot ACE too.
I do not want to reload Chassis.
Thanks,
Shain Bharati

Hi Shain
I upgraded my client's Cisco FWSM from 4.0.3 to 4.1.7 few months ago, and everything was good. I didn't have to do incremental upgrade as proposed by Cisco (best practise). This saves time because in the real world, we don't normally have the luxury of long maintenance window (in a non-HA environment).
However, if you choose to upgarde to 4.0.17, that's fine too. The upgrade has no bearing to the IOS version currently running in your C6509 chassis. This is because the FWSM runs on its' own operating system.
For further details on this, you could refer to http://www.cisco.com/en/US/docs/security/fwsm/fwsm41/release/notes/fwsmrn41.html
If you ask me personally, go for 4.1.9 as your FWSM will then be covered with the latest bug fixes.
P/S: If you think this comment is helpful, please do rate them accordingly.

Cisco 4948 issue 122-46.SG on AAA authorization

I have faced a problem regarding AAA line:

if i add this line in my cisco 4948 switch running on 122-46.SG.. The next time i telnet to the switch i get an automatic restart of the switch and all configs are lost.
IOS used:

I think it is better to move the thread to the swtiching part. They may help you better.

DHCP issue on Cisco IOS router

Hi experts,
I recently got complaints that some clients can't get IP address through the DHCP server configured on a Cisco IOS router. I turned on debugging on DHCP events and packets and I see the following logs.
Mar 22 15:33:41: DHCPD: DHCPREQUEST received from client 0100.1b63.f246.8c.
Mar 22 15:33:41: DHCPD: Finding a relay for client 0100.1b63.f246.8c on interface FastEthernet1/0.10.
Mar 22 15:33:41: DHCPD: Seeing if there is an internally specified pool class:
Mar 22 15:33:41:   DHCPD: htype 1 chaddr 001b.63f2.468c
Mar 22 15:33:41:   DHCPD: remote id 020a0000cf6050011000000a
Mar 22 15:33:41:   DHCPD: circuit id 00000000
Mar 22 15:34:02: DHCPD: DHCPREQUEST received from client 0100.1b63.f246.8c.
Mar 22 15:34:02: DHCPD: Finding a relay for client 0100.1b63.f246.8c on interface FastEthernet1/0.10.

Mar 22 15:34:02:   DHCPD: circuit id 00000000
Then it will repeat and repeat for this MAC. Any reason why the router is not assigning an IP to it? It actually happens to some other MACs as well... They are from different vendors and located on different switches... I can't really find a pattern for this problem... The DHCP pool hasn't run out and it still has available IPs in it.
Thanks

Cisco Aironet Conversion Tool Version 2.1 for Cisco IOS Software

I am trying to convert a LWAP to Cisco IOS and the tool wants to know the Admin Name*? This is a factory radio sent to me as LWAP. I cannot seem to find out what the Admin Name is, I have tried Admin and Cisco not sure what else to try.

Hi Brian,
That tool is used for the IOS to LWAPP upgrade only. The AP can be converted back to Autonomous (IOS) using the following method;
Reverting the Access Point Back to Autonomous Mode
http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp161272
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
Using a TFTP Server to Return to a Previous Release
Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
Step 3 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, and c1240-k9w7-tar.default for a 1240 series access point.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power from the access point.
Step 6 Press and hold MODE while you reconnect power to the access point.
Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
Step 8 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 9 After the access point reboots, reconfigure it using the GUI or the CLI.
From this doc;

Hope this helps!

Very high memory usage..possible memory leak? Solaris 10 8/07 x64

Hi,
I noticed yesterday that my machine was becoming increasingly slow, where once it was pretty snappy. It's a Compaq SR5250NX with 1GB of RAM. Upon checking vmstat, I noticed that the "Free" column was ~191MB. Now, the only applications I had open were FireFox 2.0.11, GAIM, and StarOffice. I closed all of them, and the number reported in the "Free" column became approximately 195MB. "Pagefile" was about 5.5x that size. There were no other applications running and it's a single user machine, so I was the only one logged in. System uptime: 9 days.
I logged out, logged back in, to see if that had an affect. It did not. Rebooted and obviously, that fixed it. Now with only FireFox, GAIM, and a terminal open, vmstat reports "Free" as ~450MB. I've noticed if I run vmstat every few seconds, the "Free" total keeps going down. Example:

Any tips, tricks, advice, on which way to go with this?

In any event, we can see that FireFox is sucking up 145MB (??!?!!? crazy...) XSun, 200MB, and java 190MB. I'm running Java Desktop System (Release 3) so I assume that is what accounts for the the high memory usage RE: java process. But, XSun, 200MB?
Is this normal and I just need to toss another gig in, or what?
Thanks

Norton reports high memory usage with firefox and it crashes often

Norton antivirus 2011 has pop up warnings reporting high memory usage from Firefox. I have been getting theem often and my computer is crashing often after those pop up warnings. Thanks

Safe mode did not help.
I have disabled ALL extensions and plug-ins, but the problem with "zig-zag" memory usage still remains (I've not tried to leave browser open for the night yet).
I think I'll do clean reinstall with completely new empty profile (without sync'ed information) to try this out. If this works, I'll start adding stuff (configuration, sync, features, etc) to see what causes the problem.

Extremely high memory usage after upgrading to Firefox 12

After I upgraded to Firefox 12, I began frequently experiencing Firefox memory usage ballooning extremely high (2-3GB after a few minutes of light browsing). Sometimes it will drop back down to a more reasonable level (a few hundred MB), sometimes it hangs (presumably while trying to garbage collect everything), and sometimes it crashes. Usually the crashing thread cannot be determined, but when it can be, it is in the garbage collection code ( [https://crash-stats.mozilla.com/report/list?signature=js%3A%3Agc%3A%3AMarkChildren%28JSTracer*%2C+js%3A%3Atypes%3A%3ATypeObject*%29] ).
I was able to capture an about:memory report when Firefox had gotten to about 1.5 GB and have attached an image.
A couple of things I've tried. I have lots of tabs open (though the Don't load tabs until selected option is enabled), so I copied my profile, kept all my extensions enabled, but closed all my tabs. I then left a page open to http://news.google.com/ and it ran fine for several days, whereas my original profile crashes multiple times a day.
I also tried disabling most of my extensions, leaving the following extensions that I refuse to browse without:
Adblock Plus
BetterPrivacy
NoScript
PasswordMaker
Perspectives
Priv3
However, the problem still happened in that case.
Don't know if any of this helps or not. I'm looking forward to trying Firefox 13 when it comes out.

hello, thanks for reporting back with detailed information.
from a brief look at your extensions i don't recognize any known (to me at least) memory leaking ones. in the last weeks there were also reports about the java plugin causing high memory consumption in combination with firefox 12 - in case you have it installed in firefox > addons > plugins try disabling it for a few days & test how firefox is behaving with many tabs.
& although probably not related to the memory problems you could update your graphics driver to get better results with hardware acceleration in firefox - this is the latest driver by intel for your model & os:
