Why does a VRRP master with preemption disabled regain master state after the reboot ?

Q: Why does a VRRP master with preemption disabled regain master state after the reboot?
A: This issue is found in the following scenarios:
1. When spanning tree is disabled on either of the VRRP controllers but enabled on upstream switch(es).
2. When the controller(any one VRRP controller) and upstream device(s) run different versions of STP.
3. STP convergence time is different across the VRRP controllers.
In these scenarios, rebooted vrrp master is expected to come back as vrrp MASTER as the link takes some time to converge and fail to receive VRRP advertisement packets from its peer and may roll back to MASTER.
Trigger for this is, since STP is enabled on intermediate switch and disabled on controller, switch is taking some time ~30 secs to converge the link while port on the controller has become UP and fail-over to Master due to
not receiving VRRP advertisement packets
In all these cases, it is advised to enable holdtime to mitigate issue. Holdtime has been introduced to tackle this issue in the "preemption disabled scenario".
Configuration via CLI:
(controller) (config) #vrrp <id>
(controller) (config-vrrp)#holdtime
Description:
The VRRP virtual router does not begin listening to advertisements until the holdtime expires. If your deployment includes a VRRP master with preemption disabled and an uplink switch is running RSTP, a higher value will prevent the VRRP master from regaining the master state after it reboots.
Range: 30 - 120 seconds
Default: 45 seconds

Hey Jim,
Thanks for the follow-up. Here are some more details:
OS - 10.8.2
FCP X - 10.0.7
I can't update either of these because of my Avid installation.
Something else I didn't mention – this happens in a 4K project. Notice how a default Zoom title looks:
Lines 1 and 2 are almost stacked on top of each other.
Here's my title style:
Here's what the title looks after I apply the title style, modify Line 1, and remove the contents of Line 2:
And here's how it looks in the exported master file MOV:
Notice how it's pushed down?
Then I decided to make a 720p project. No more title problems.
So if you have some 4K footage, Jim, give it a go. Or if there's another 4K-er out there, try this and let me know.
Thanks!

Why does my Elements 12 ask me to enter Program Key after the product has been used and registered

I have had Elememts 12 for several months ... when I bought it ...I downloaded the program and registered it ... now ... every once in a while the program asks me to enter the Key number as if I never registered it ... also sometimes I get a message about my 30 day trial ...

I purchased Elements 12 not the Premier addition .... the disk Elements 12 comes with a trial version of Premier ... I did not install the 30 day trial version .... maybe t is Adobe trying to sell me the Premier addition ... I will pay more attention the next time the message comes up ... after reading some of the posts, I think that is what is happening ... I will have to wait ... someone wrote that they had the same problem and after a while, the message stopped appearing .... as I indicated .... I will look more carefully the next time I see the message...
Thanks again

I am trying to get through all your recent replies to go back to your post numbered 8.
1. Go to Control Panel/Programs and determine if you have Premiere Elements 12 and Photoshop Elements 12 installed.
2. When you have gotten the try out dialog, what program is mentioned in the dialogs - Premiere Elements 12 or Photoshop Elements 12?
3. The fundamental question is what did you purchase
a Photoshop Elements 12
b. Premiere Elements 12
c. Photoshop Elements 12 and Premiere Elements 12
From what you wrote it sounds like Photoshop Elements 12. Premiere Elements 12 seems to have come along as a tryout.
4. If Premiere Elements 12 is a tryout, after 30 days from first install of it, you should not be able to use it without a purchased serial number specific for Premiere Elements 12.
5. If you have no interest in Premiere Elements 12 tryout, uninstall it if it is installed. If it is not installed, then it is not the cause of your trial messages. But, I offer you this thought. Are these really License This Product/Continue Trial messages or are they really promotional dialogs (ads) put on your computer by Adobe who knows you have Photoshop Elements 12 and are trying to get you interested in Premiere Elements as well?
Please review and consider.
Thanks.

Add On...All my encountered with tryout pop ups have been as described and restricted to purchase Photoshop Elements 12 and Premiere Elements 12 purchased as bundle.

Why does fix capitalization work when there is only one space after the period in pages 09?

why does fix capitalization work when there is only one space after the period in pages 09? For example: "Turn on 3rd St. After the traffic light." There is only one space after the period in "St." shouldn't it only auto correct after TWO spaces..?? the word After, should be after..

You may also use a noBreak space after the period at the end of the abbreviation.
If I remember well, in such case the capitalization will not apply.

Why does apple sell phones with "INTERNATIONAL WARRANTY" when they cant service the phone in India, which has been bought outside India ? Whats the use of their registered service centers ?

i got my iphone 5 as a gift from my friend when he went on a business tour to Dubai. i have a got problem with the native camera app and i contacted the customer care more then 3-5 times and they finally gave me a solution to check with the service centers avialble in my city. i went all the way there from my place and they said you cant service your phone over here since its has been bought outisde India ! then why do APPLE ship phones ? why do they have REGISTERED SERVICE CENTRES in India ? why do they sell apple products with the tag INTERNATIONAL WARRANTY ?

There is a problem insofar as you did not buy the phone.   Any warranty would therefore apply to the buyer.   What I would suggest is this ...
With the receipt in your hand, telephone the store where it was purchased. Explain the situation and ask them how you should proceed.    You may find they'll only deal with your friend but if he/she is willing, it can still be pursued in your friend's name.
Once you have agreed a way of getting it serviced you will need to return the phone, and as I suggested, by a registered post system that requires proof of delivery. Most postal services do this.
Pack the phone, preferably in its original box and surround it with extra packing. You do not want anyone to have grounds to say it was further damaged in transit.
Include a dated letter stating what the fault is and affix to that a copy of the receipt.
I hope you are successful.   Thank you for the star.

HT5824 why does my ipad say user name disabled, but on all other devices i can pog into itunes and icloud using my user name

why does my ipad say user name disabled but i can use my user name to log into itunes and icloud on other devices

At this time there is no "solution." You'll simply have to wait the 90 days to re-enable iTunes Match.
For now here is my suggestion. In your User Account, in OS X, sign out of whatever iTunes Store account you are signed in with. Then sign in with your store account and leave it at that. Now sign out of your OS X User Account, sign into your wife's OS X User Account and sign into the iTunes Store with her Apple ID (if necessary sign out of the account first).
Now, you can go back to your OS X User Account and attempt to enable iTunes Match. You will probably get the "wait 90 days" message. If so leave it, mark your calendar, and wait for the 90 days to expire. You can try contacting iTunes Store support at <https://expresslane.apple.com> if you wish, but I really do not know how useful that will be.
Incidentally, you get the message to pay for the service when trying to enable it on your wife's Apple ID because the service has not been purchased using that Apple ID. iTunes Match is designed to be a single-user service that is never signed out of and is associated with one, and only one, Apple ID and a regional store.

Why does a yield sign with an ! sign come up on some photos

why does a yield sign with an ! sign in the middle come up on some photos

That means iPhoto has broken the file path/link to the original image file. Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
iPhoto 8 (09) and earlier- run the options indicated
iPhoto 9 (11) and later- run Option #4 to rebuild the database
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager (iPhoto 8 or earlier or IPhoto 11 and later) and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the
File ➙ Rebuild Library (iPhoto 8 or earlier)
or
Library ➙ Rebuild Library (iPhoto 9 or later)
menu option to rebuild the library.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Why does my Mac boot with a Grey screen and a globe?

Why does my Mac boot with a Grey screen and a globe?

Usually means you don't have a bootable system installed so the OS is looking for a bootable system on the network.
Does the computer eventually start up shortly after the globe appears? If so then open Startup Disk preferences, select your boot volume and click on the Restart button. If this is not the case then you need to reinstall Snow Leopard.
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

Can anyone help me? Why does my ipad kick me out of FB? Sometimes to the 'settings' page and sometimes to the desk top? I would like to know why this happens and what I can check or change to make it stop. I have 50.8 GB of capacity available; it is version IOS 5.1.1; model MC497LL. It is WIFI and internet via AT&T? Can anyone give me some clues on what to do; or change in settings??? Thank you very much!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Why does't apple allow you to read your iBooks library over the web from a browser or me account?

Why does't Apple allow you to read your iBooks library over the web from a browser or me account? I have time to read during the day via a browser, but not by Ipad or Iphone. I love the features that iBook offers, but I have had to settle for Google books which is slow to upgrade its features. I just want to be able to highlight, copy and past and make notes and also have the option to read a book in a browser like google books.

Wow.. I'm almost sorry that you spent so much time writing that post.
Unfortunately, it would have much more impact if it were true.
Just because you don't know how to do something... that doesn't mean it can't be done.
I do what you say can't be done every day.
You just need to put your iPod into manual update mode, and everything will be fine. You songs won't be greyed out, and you can play them with no trouble at all.
So, next time you need help with something, just ask for help and we'll help you. It'll certainly make yourself look less foolish this way.
Ranting and bashing Apple for no reason isn't going to win many people over.
