IPv6 - No buffer space available

Anyone else seen this IPv6 weirdness:
6to4 tunnel to Hurricane Electric. Mac Pro is the router and tunnel endpoint (gif0). ip Protocol 41 passed through various routers/firewalls, etc.
sysctl'd ipv6 forwarding on and RA.
statically assigned /64 either end on subnet 2001:feed:d00d:1f04:: for tunnel
local wire net /64 subnet 2001:feed:d00d:1f05:: (I made up these example addrs, so don't get all bothered
rtadvd configured for en0, with :tc=ether.
en0 assigned a /128%en0 address in Control Panel. Perfect, works
great.
After about 8 hours, connectivity dies, err= "Sendmsg: No buffer space
available".
FYI: sysctl kern.ipc.maxsockbuf: 4194304
I can still ping locally and hit either end of the tunnel, but no external addresses, as routing has stopped. ipv6 and icmpv6 are not transmitted or received to/from routed nets. Inbound traffic is dumped on the floor, with no icmpv6 message, such as a type 1 (no route available).
What (semi) fixes it is to NOT assign the /128%en0 in Control Panel, instead ifconfig the address for en0. However, this stimulates a bug in rtadvd where it assigns an incorrect link local fe80:: as the default gw, if the Control Panel IPv6 is set to Auto. Even if rtadvd is configured correctly, a bug overrides the
rtadvd.conf en0 addr and advertises an incorrect link local addr as route 'default'.
netstat still shows the correct default route, gif0 is fine in terms of routes and so on and ip6fw rules are flushed for the purposes of this test.
Rock and a hard place .
thanks!

Hi Ananda and Vyara,
Thanks a lot for your replies!
Restart did not help (including restart the machine).
From the google search I also hit the same MS page. Obviously it did not help either. I guess there is some problem with connection to the SQL server. I checked the tcp connections and another server which is running well has more connections than this one.

Hart

No buffer space available

We are executing a program that use a lot of memory, because that program read a big struct of a database in classes. It's executing properly in Win2000, but in Windows 9x ocurr this error:
No buffer space available (maximum connections reached?): connect
Anybody help me?
Thank you very much?

Have you tried using the -mx and -ms settings passed to java?
I've run very memory intensive things on 95 with jdk 1.2.2 and 1.3.1 and I've had pretty good luck.

"SocketException: No buffer space available" on a non-blocking socket?

Why do i get "SocketException: No buffer space available" on non-blocking DatagramChannel.send()? According to the docs, it's just supposed to return 0 as the number bytes written, no?

Why did you crosspost this when it had already been answered?

Hostapd `EAPOL TX: no buffer space available' error

Hi guys, I have just configured hostapd with NAT to let my smart phone use wired network. At first, it worked normally. But recently I found that sometimes, the connection between the AP and my phone seemed to fail after some time, especially when there are some other devices connecting my AP. Here 'fail' means no packets can be transfered between the two devices and any new device cannot establish a connection with the AP. It seems that at that time, my wireless device only broadcast an SSID, and when I look at the terminal, there are nothing uncommon except some `nl80211: EAPOL TX: no buffer space available' errors. When I tried to let my AP work again, I found that seemingly any actions, except restarting my laptop, does not work. I tried googling, but no luck.

Bonjour,
Toutd'abord merci de votre réponse!
A première vu mes fichiers sont bien fermé après écriture, faudrait que je fasse un étude plus approfondie pour en être sûre à 100% mais si le problème viendrait de là je pense que mon erreur arriverait plus souvent que toute les 1 à deux semaine, en effet ma base de donnée tourne en permanence 24/24 7/7 en service sur windows pour recevoir les données provenant du moteur (les données sont stocké dans un mémoire cyclique dans la base de donnée). Je vais consulter plusieur fois mes données par jours en me connectant à ma base de donnée avec mon programme et ensuite je me deconnecte de la base de donnée quand j'ai vu ce que je voulais voir! Et ce plusieur fois par jour!! Mais certaine fois (toute les 1 à 2 semaines) je ne peux plus me connceter à cette base de donnée car j'ai cette erreur 10055 qui apparait, je dois donc redémarrer la base de donnée et le problème est résolu pour un certain temps à nouveau!

10.4.11 and "No buffer space available"

Hi!
Just updated to 10.4.11 and now i can't connect to internet.
My AirPort works, i can ping the router, but thats all.
When i try to use Safari i get this msg:
"POSIX error: "no buffer space available" (NSPOSIXErrorDomain:55)"
Anyone have a clue?

Im running 10.5.1. I use a general purpose utility called Cocktail and was fiddling with the network settings. On reboot, opening up Safari resulted in the "..no buffer space NSPOSIXErrorDomain:55 message. Deleting /Library/StartupItems/Cocktail fixed it.

ASR multicast: Could not write data: No buffer space available

I am trying to multicast a disk image to multiple iMacs. Here is my plist config for the server:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
          <key>Data Rate</key>
          <integer>12000000</integer>
          <key>Multicast Address</key>
          <string>224.77.2.121</string>
</dict>
</plist>
I use the following command to start the server:
sudo asr -source labmac.dmg -server multicast.plist
The terminal responds "Ready to start accepting clients"
Then I go to one of the iMacs that will receive the image. I am netbooting the client off of the same server that is multicasting the image over ASR. I try to start the imaging process by issuing the following command on the client:
sudo asr -source asr://server.ip.add.ress -target /Volumes/Macintosh HD -erase
The command is accepted, confirms that I would like to erase the drive, and then says "Restoring" but no progress shows.
Back on the server, the terminal will output the following continuously until I cancel the multicast:
Starting stream Sun Feb 10 15:55:10 2013
asr: Could not write data: No buffer space available
The multicast seems to be working because the entire network gets bogged down, so why is it that it is unable to transfer the image data?

Did you end up figuring this out? i'm on the same boat

Hmm no that's not the problem unfortunately, i can start the daemon without problems, but it just crashes now and then after a while (sometimes more than a day after it was started).
why you are using acpid ?
Because my laptop exposes most of it's special keys (lid, brightness, volume etc) as acpi events, and i need a simple way to capture and script those.

Hi Khushi，
According to your description, your snapshot replication job fails and you come across the error related to TCP Provider. Based on my research, the issue could occur as the following two situations.
1. OS runs out of memory for TCP buffers. When people use the two switch: the /PAE switch in the c:\boot.ini file and the /3gb switch in the boot.ini file. If the applications require many OS resources, such as by opening many TCP connections, this can cause
the OS to run out of memory for resources like TCP buffers.
2.OS runs out of available TCP “ephemeral” ports. When the client machine is opening many TCP connections and is running Windows Server 2003, Windows XP, or any earlier version of Windows, it may run out of TCP “ephemeral” ports.
To work around the issue, please follow the two solutions as below.
1.Remove the /3gb switch from c:\boot.ini. The root problem in this case is memory pressure on the OS, so removing the /3gb switch will give more memory to the OS and will alleviate this problem.
2.Make more ephemeral ports available following the steps in the article:
http://support.microsoft.com/kb/196271
For more information about the process, please refer to the article:

No-drop buffer space?

**Edited for clarification
When configuring a no-drop queue it carves out 90240byte buffer space for it. All remaining buffer is assigned to the default class. I cannot find any document that says this specifically, but I am assuming that if that 90KB buffer is full it will use additional buffer space from the default class if available? Is this a correct assumption? If this assumption is incorrect, and 90KB is all it gets, then wouldnt enabling a no-drop queue be detrimental if there is no other traffic on the switch and you assigning no-drop to all traffic?
Maybe I can clarify the question. When configuring a no-drop class, as shown in the table below, it carves out 90.204KB of the available 478KB ingress buffer, for that system class. Does this mean that the no-drop class gets 90.204KB of buffer space and that is the limit or will the ingress buffer use all of the 478 total KB across all other classes in the event there is no other traffic present?

After some research I have answered my own question. By enabling pause no-drop it has sliced my available buffer from 470KB to 90KB. It now sends TX pause frames out at 37KB and Resume frames at 17KB. It will not use available buffer space in excess of 90.24KB It appears I will need to use a command similar to "pause no-drop buffer-size 442000 pause-threshold 300560 resume-threshold 243100”. My problem now is, what to set all those values to. I wonder what percentage of buffer usage I should have it send pause/resume frames.

3750 - Default buffer space for ingress queues

Hello,
I read the Cisco Catalyst 3750 QoS Configuration Examples white paper and I have a few questions:
1. On page 24 it said that "TheÂ IOSÂ allocatesÂ defaultÂ spaceÂ inÂ theÂ bufferÂ toÂ queueÂ ingressÂ packetsÂ afterÂ QoSÂ isÂ enabled." Is there a command to see the size of the default buffer space?
2. "Â 67%Â ofÂ theÂ totalÂ available
memoryÂ forÂ ingressÂ queueÂ isÂ allocatedÂ toÂ queueÂ 1Â andÂ 33%Â isÂ allocatedÂ toÂ queueÂ 2." I thought that the default buffer size is a portion of the total memory and queue 1 and 2 share the defualt buffer size.

sh mls qos queue-set command can be used to verify the details of the buffer size.3750 has a lot of internal buffer for QOS to use

I was backing up my iPhone and importing photos onto iPhoto at the same time , then suddenly it says no more space available (i had 48GB before i do this and now i have 18GB) i can't find the back up or the photo anywhere , how can i delete them ?

Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown asBackups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size with the largest at the top. It may take a few minutes for ODS to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

I know many have this issue but i can't find a solution to the problem. i get message saying insuffisiant disk space in the volume iPhoto library and i have plenty of space available. i have the new macbook pro with retina display.

I know many have this issue but i can't find a solution to the problem. i get message saying insuffisiant disk space in the volume iPhoto library and i have plenty of space available. i have the new macbook pro with retina display. i have never seen this message before and i have 2 other macbooks and have had many other also. i am assuming this is a problem with the new macbook retina. does anyone know the exact fix to this issue? i have seen many sugestions to try to fix this issue but none have solved the issue for anyone that i can find in the Apple Support Community. thank for looking into this in advance.

Actually your suggestions are the ones that i have tried. i have seen that you have tried to help others with this issue and the only one that i could find that said they found the problem said that it was an ilife update issue and it fixed it and i have no available updates. i know it has to do with something in photo stream because it happens when i create a new library and it is loading the photos but i get the message before i reach the maximum 1000 photos. so i've tried updating, new library(first backing up photos and then deleting them from iPhoto), reinstalling OSX many times, running disc utilities. I called Apple the first day i had this issue and i was the first person to call them for support with the retina display and i actually had it escalated to a senior advisor and we thought we fixed the problem but we did not. i am pretty fluent in dealing with troubleshooting these type of issues and this is the first time i'm reaching out to the community. i figured now that the retina has been out some time now that there would be an obvious answer to this issue. thanks for the quick reply.

I have an iPod 4s and I am trying to update to IOS 6.1.6. I keep trying to download but it will not allow me to click download and install. I have checked my storage and I have more than enough storage space available. Do you guys have any suggestions?

The only available, signed, iOS, for your iPod, is iOS 7.1. That's why you can't install iOS 6.1.6.
