Network timeout only for library upgrade items

I purchased an upgrade of my library, which totals 430 songs. The purchase went through fine, but when I would try to "check for downloads" so I could download the items, I kept getting "network timeout" errors. I ran the diagnostics, and after sending a support request, I was told it was probably my third-party firewall (even though it was properly configured and I had always been able to download without a problem).
I uninstalled the firewall and related security software, and when I continued to have trouble I was advised to disable all startup items. I did that, and even disabled Windows Firewall (which also was properly configured for iTunes), and I continued to get the same result.
I re-enabled the startup items and the Windows Firewall, and, just as an experiment, I tried purchasing an album from the store. The purchase went through and the album immediately downloaded without a problem. After that, I tried again to "check for available downloads." (Incidentally, iTunes shows there are 430 downloads available.) I again got the same error.
It seems clear, at this point, that I am able to connect and download, but there is something wrong on the other end of this deal that is preventing me from downloading the music I paid for. I am getting extremely frustrated, because by now I have spent hours and hours trying to get the music I paid for.
Anyone else experience anything like this, where the "update library" purchases seem to be the only thing you can't get to?

I was finally able to have the issue bumped up to a Senior Tech, who was able to help me. According to him, some ISPs have a problem with very large downloads. Over the course of several days, we broke the library upgrade into smaller chunks, with him placing the songs into the queue.
We did have a further problem at one point where some of the "upgraded" songs were duplicates of the m4p files (rather than the unprotected files). We never figured out the problem there, but he re-placed all 430 of the upgraded songs in my download queue, and this time the whole set of 430 downloaded.
So I'm not sure why it would work that time, if it was my ISP causing the difficulty, but whatever. It only took about three weeks of work and a hundred bucks or so, but I now have the items able to be upgraded.
I have to give a big thumbs-up to the techs I finally dealt with when I took matters into my own hands and called AppleCare--going through the ExpressLane was useless and a waste of time. Notody even reads the emails--all you get are form replies telling you to do what you already say you have done.

Still gettting error 33162 despite increasing network timeouts

Hi All,
I have an application that frequently displays error code 33162. I followed the advice at http://digital.ni.com/public.nsf/allkb/C4E77D7E9BECBAFE86256C6200544289 and doubled my network timeouts to 4 seconds timeout and 10 seconds initial connect timeout. I still get the error however. When I get the error the block diagram briefly flashes on one of the blocks, but it's too fast to really see.
Any advice on how to solve this error condition?
Thanks,
Sean

Hi,
I am having the problem occur repeatedly again today. My fieldpoint hardware is cFP-2000. I am currently seeing repeated 33162 errors, so many that I have to stop my application.
The attached screenshot shows where the error is occuring. We'd really appreciate any advice on this problem. Our fieldpoint modules are located close to some heavy AC equipment, so hopefully the EM fields from this are not affecting them.
Thanks,
Sean

Idle Processes, network timeouts ISL

Is there any way to determine the length of time a client or process has
been idle rather than merely if it is idle? How does the ISL determine
which connections have been idle when invoking it's network timeout value?
Regards,
Steven M. Hill

Thanks Per!
The T_CLIENT class contains a TA_IDLETIME function which returns the no.
of secs since a client last issued an ATMI call. I'm searching the
documentation for MIB programming but it's not that clear, so I'll have
to proceed by trial and error :-)

Hello Steven,
I haven't worked with the ISL but if it is anything like the WSL I would try looking at the T_CLIENT class in the TM_MIB. There is an attribute called TA_IDLETIME which may be what you're looking for.

ITunes "network timeout" when I try to login

I can't authorize my laptops in Itunes because every time I try to login it comes back with a "network timeout" error. I cannot login to iTunes at all tonight. Anyone else? Running Windows 7 64.

Same with me. I can browse the store and try to buy an app but I get a connection timeout after it prompts me for my account password. I can't even purchase anything through my phone on the 3G link.

Network Timeout freezes InDesign

A Win7 SP1 64bit PC is running InDesign CS5, and while working on a file, a user experienced a "network connection" error, and then InDesign froze, with no chance of recovery.
Is there any way to prevent ID from freezing when a network timeout issue occurs?
Why does it need to freeze anyway? Why can't it simply halt whatever task it was trying to perform?

I think there is no question, scientifically or unscientifically, that we see far more reports of file corruption with networks than without.
Networks are complicated beasts, and they have many more possibly failure points than local disks do. (On the other hand, people with network storage are much more likely to have reliably backups; at least that's been true historically before the advent of both popular Internet-based backup and Apple's Time Machine). It's also the case that medium to large sites work almost exclusively with networks (though they may use database-driven document storage for which the traditional InDesign network-averse guidance may not apply), and they tend to deal with more documents than individuals do.
I think the single most definitive point in your favor of your position is this text from the CS5 help, Recommended workflow for InDesign documents:
You
can improve performance and prevent many problems by establishing
a good workflow to use with Adobe InDesign.
Open documents locally
Before you open
a document stored on a network volume or on removable media, copy
the document and any linked graphics to your local hard disk. The slower
access time and data transfer rate of a network volume or removable media
can cause data to become lost or corrupted, possibly damaging the document.
However, be aware of overriding someone else’s work if you copy
the local files back to a network server.
But that doesn't say networks are unsupported, it just says they may not be good.
But the person who wrote this was hopelessly naïve — network are a critical part of any modern business computer setup that is larger in scope than a sole proprietorship. And anyworkflow that expects users to copy files off the network to local disk and back is patently ludicrous. As the above acknowledges, copying them back is frought with peril.
Furthermore, the operating system vendors have expended no small effort to make networks mroe and more seamless and well-integrated, and to try to make them nearly indistiguishable from local disk—except. Except when they don't. Except when they can't. Except when applications need to know more about the underlying substrate of the filesystem, need better timing information, need to do things like memory-map files into RAM with guaranteed perforamance, etc. Though I am a bit skeptical that InDesign has any such needs...
Probably a good summary comes from a John Nack (Photoshop evangelist) blog post from 2008 (and networks have only become more popular), where he quotes an unnamed Adobe engineer, http://blogs.adobe.com/jnack/2008/06/filesaving_issu.html:
Directly writing to a network filing system adds a level of complexity,
which includes timing issues, network noise, performance, and other
potential issues. We’ve occasionally run into bugs with different
configurations/combinations, but as there are too many variants for us
to reliably test and certify all the clients, servers, hardware and
software, we recommend the safer course of working with files locally
and then copying them up to a file server when you’re done. While
directly reading/writing to network file systems should work in theory,
and while we do some limited testing in the most popular configurations
to verify that it does, we can not certify that it will work reliably in
your configuration.
But, of course, what do we mean by "support"? I am, by the way, interpretting your statement "not designed for working over networks," as "networks are not supported," and that may not be fair of me.
To me, "supported" means there is a reasonable expectation of the software working in the scenario, that Adobe will address bugs raised to them over the issue (rather than closing bugs saying, "at your own risk, sorry, bub!"), and Adobe will make a reasonable effort to keep it working. I think the situation with networks does qualify.
Unfortunately, it's hard to find anyone to say so. In part, I think, because there are so many variables nobody wants to be pinned down saying "it'll work" because you'll always eventually be able to point to a case where it won't. And the above blog post (part I didn't quote) talks about how a problem is really due to a bad interaction with Adobe product and MacOS X 10.5.3, which was later fixed by Apple.
Anyhow, we can also find plenty of evidence of Adobe having accepted and fixed bugs that relate to network behavior in InDesign. So I'm pretty confident that network use of InDesign si well-supported. But I certainly wouldn't say it was rock solid.
Hmm, this is kind of long. I will address the OP's issues in a seperate post.

Westell 327W Network Timeout

I'm having problems setting up Apache and SSH with my Westell 327W.
I have Verizon DSL -> Westell 327W Modem/Router -> Ubuntu Server with Apache Web Server and SSH Server.
The Ubuntu Server with apache and SSH is the DMZ Host.
Apache and SSH will work good for 5-10 minutes, then when you click on a link or do anything from the apache webpage... Firefox says Connecting to XXX.XXX.XXX.XXX, then it will say Page Load Error. Network Timeout. The server at xxx.xxx.xxx.xxx is taking too long to respond.
I putty (ssh) into the Ubuntu server, everything will work good for 5-10 minutes, then putty will freeze up and say Putty Fatal Error. Network error: Software caused connection abort.
Apache or SSH will NOT work for 1-2 minutes. Firefox will say Network Timeout and SSH will not connect at all.
Then, everything will work again for 5-10 more minutes... then go down for 1-2 minutes, over and over and over....
Where can I find help for the Westell 327W Custom Firewall Rules? I dont have a help section on my 327W and cant find any information about making my own custom firewall rules.
I've read my problem occurs because of my firewall rules. The router drops the session because it drops it out of the state table or something like that?!?!?!? But I thought setting a PC as the DMZ host would put it outside of the firewall and the firewall rules wouldnt apply to the DMZ host?!?!?!?
PLEASE HELP! Thanks!

Ok, I thought so.
#1 In you are using GNOME, go to System >> Admininstration >> Networking.
#2 In the general tab make sure your network card is active.
#3 Select your network adapter and press properties.
#4 Make sure your network card is enabled.
#5 Change the configuration from DHCP to static (OR if it is already set to static)...
#6 For the IP Addres, you can set any number that you want to but not: 0, 1, 15 to 47 OR 255.
Such as 192.168.1.6
#7 Enter in the Subnet Mask of: 255.255.255.0
#8 Enter in the default gateway of: 192.168.1.1
#9 In the DNS Tab, enter in the DNS Servers that you want to use.
b) If you desire to, you may enter in the DNS of 192.168.1.1
c) OR the DNS Server address(es) that are in one of your router's screens. Maybe at Advanced -> DNS ?
#10 In your router, forward to the IP Address that you have setup on your computer.
This should resolve the issue. If not, in your router go to Advanced... In Advanced, if you see anything about UPnP (Universal Plug and Play) go there.
If UPnP is turned in the router, I would recommend turning that feature off.
If in Advanced you do not see anything about UPnP, please show a screen shot of the Advanced Screen...
I state my source(s) about setting a Static IP.
a) URL: http://forum.portforward.com/YaBB.cgi?num=1116577357

and..
b) http://forum.portforward.com/YaBB.cgi?num=1119584531

As to why turning off UPnP: Because it opens ports automatic in the router, and you can not have over lapping ports.

Trying to download ios5 to ipad and getting network timeouts also showing 15 hours to download. I have turned off firewall but still happening

I am trying to download the latest iOS 5 for my ipad and husbands iphone 4 but firstly it is coming up saying 17 hours then I am getting network timeouts!! I have turned off my firewall etc but still does the same. I have the latest iphone 4s and I am wanting to use cloud etc but can not due to this, can anyone help

Have you turned off all your firewall and antivirus software ? If that doesn't work then you could try downloading the iPad update via a browser : https://discussions.apple.com/message/16703914#16703914
And for the iPhone 4 :

Slow network timeouts, page loading when host is bad

I just got a new iMac, and it takes a long time to timeout network connections to bad hosts. For example, on the Mac it's replacing I can just type "apple" into the Safari address bar, and since that's not a real address Safari would be smart enough enough to almost instantly replace it with "www.apple.com". The new iMac takes 30 seconds to do this. It causes a number of web sites to load slowly since quite a few seem to pull non-essential resources from other servers that aren't always up (ads, scripts, etc.).
I can verify that it takes 30 seconds by running "time ping apple" in the Terminal, which takes almost exactly 30 seconds each time before saying "cannot resolve host". The old Mac fails instantly. Can someone else try this on Snow Leopard an let me know if it's fast or slow for you. I restarted in bootcamp/Windows 7 and I do not have this issue there: 'ping' times out right away.
I don't think this is a DNS issue since the two macs have the same DNS server. Also, "nslookup apple" on the new Mac immediately says "can't find apple," like I'd expect.
Any ideas on what causes this delay? Is this a configurable network setting somewhere? The new Mac is on Snow Leopard; the old is on plain Leopard. I'm not going through any proxy servers or running any ad blockers or the like.

You can speed up iWeb by having each website on a separate Domain file and dividing up

Searching for networks - timeout

Hi,
In the US, in Roaming, I am having trouble connecting to a network.
In automatic, I can't get a network.
In Manual a get a timeout - try again later msg.
However, people in the house has network connections available and are able to communicate..
Any tricks to extend the timeout period in manual search mode ?
Any other tips (I have already reset the phone (even took the bat out & in) but the situation is the same) ?
Thanks/ Brgds

Hi John,
After my first post, I left my machine for about 10 hours and when I came back the connection has since been steady. I'm beginning to think the whole problem may have been with my Internet provider .... since I don't know I'm still going to take your recommendation and upgrade the router so that it can keep up with the new modem and speed boost.
I guess I had tried everything except for patience

Systemd issues. mdadm-raid and nfs with no network timeouts.

Hi,
I'm migrating my final two machines to systemd now and ran into some troubles.
Issue 1:
I've got a md-raid that systemd tries to 'start' (dev-md0p1.device).
This obviously doesn't work since there is nothing to 'start' and it just times out after 90 seconds thus entering emergency mode.
From there I can mount /dev/md0p1 just fine.
Is there any way to make systemd just mount the device and do nothing else?
Issue 2:
I'm not booting my laptop with network, but has a NFS-entry in fstab.
systemd still tries to mount it, delaying the boot with 90 seconds.
x-systemd.device-timeout doesn't make any difference at all.
Any way to fix this? They say it shouldn't try mount any network devices when no network is up...
Thank you for all help!

Ok, if someone else encounters these problems:
The nfs-shares need the option "command=systemd.automount" for systemd to care about them apparently. Normal auto is not enough.
Systemd makes the md0-device busy during boot at about the same time it tries to mount md0p1 making it busy and time out.
Running systemctl --system daemon-reload makes it reload everything that hangs, 4 services/devices in my case.
Not a good solution, but I'm pretty fed up with systemd now.

Network timeout, can't figure out why.

I have a problem that my network time out. I first encoutered this when i tried to use the oauth functionality that i program for my web app and it timed out.
I tried to wget google and it timed out too:

Also, my website works and the ssh connection works.
I really don't know wat is happening.
Thanks in advance for your kind help and time.

Based on the pasted output of wget, it is trying to connect to IPv6 of google.com (which leads to timeout) and then it tries the IPv4 which succeeds.
I guess you do not have IPv6 connectivity. You can disable it as shown here.

Network timeout MacBook Pro

So I have a april 2009 13" MacBook Pro. I was using on campus when it automatically disconnects from the campus wifi. The networks appear in the airport scans, but when tried to connect, it just says connection timeout. All other wifi elsewhere work. inputs?

I was having this issue on two macbooks that I have. One was on Lion 10.7.2 and one Snow leopoard 10.6.3. Both would not connect to my Airport extreme. The only thing that worked was deleting key chain from keychain Access and then reseting SMC. Hope that works for you. Good luck.

OVM Server in a VLAN has network timeouts

Hi community.
I have the next issue in OVM Server configured in a VLAN.
When the the users accessing the VMs out of the LAN, the communications presents timeout and the session not work well.
If a ping is sent since WAN, there timeouts by 5 seconds and then the communication is reestablished.
If the same test is running in the LAN., not there any problem.
If the ping is sended since VM to WAN, not there any problem.
Is probably a Network communications problem??? or is probably problem in the OVM Manager or OVM Server configuration
The OVM Manager version is 3.1.1
The OVM Server version is 3.1.1.
Thank you for any suggestions.

Hello!!
Maybe it could be ovs-agent service from the server not communicating correctly with VM Manager??
You should login to server and see what command "service ovs-agent status" returns!!
If everything is running maybe a "service ovs-agent restart" could resolve something...
Also check that there aren't locked processes...under "/var/run/ovs-agent/" check that there is NOT any ".lock" file.
Greets!! ;)
