Status: RESOLVED INVALID

(Thunderbird :: Mail Window Front End, defect)

Description

Attachment: thunderbird-mail_2sorts_of_spam.png

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170824053622

Steps to reproduce:

Write a mail / write in Libre Ofice


Actual results:

TB freezes for about a minute, when a spam message comes in, mostly while I write a mail. When I'm using Libre Office then same freezing happend with Libre Office simultaneously.

The issue happend since I install TB first on this laptop, 2015. 
I've tried the German support forum first and tested several things:

What I've tried before without any effect:
- Start without Add Ons;
- turn off and delete Kaspersky Internet Security (KIS);
- repair folders;
- reinstall Thunderbird;
- Open TB as administrator.

It maybe depends on the two sorts of spam markers in my webmail account and my operating system (Windows 10 Professional). 
My Provider is all-inkl.com

If you want, I can open a test account for you. A picture of the two sorts of spam flags is attached (Sorry, in German, but "server" and "Thunderbird" fits ;-) ).

This issue doesn't happens at all my other pc/laptop (with WIN 7, Vista, XP), all with KIS, Lightning, Libre Office etc.
Only with my WIN 10 Pro -ASUS-Laptop.


Any idea?! F.e., what library Libre Office and Thunderbird use together?!


Expected results:

No freezing at all :-)

Thank you!

I've created a test account for you with [e-mail].

If you give me a mail adress, I'll send you the login data

Some questions
- Check Windows task manager - when Thunderbird freezes, is how much CPU and memory are Thunderbird using. And are there any other system processes?
- Please measure the number of seconds of freeze
- what is size of training.dat file in your Thunderbird profile?
- do you have many filters?
- and if you have addressbook whitelisting enabled in Account>Junk Settings, how many contacts in your addresses books

And Please test the following ... Start *Windows'* safe mode with networking enabled
- win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
Still In Windows safe mode, start thunderbird in safe mode
- https://support.mozilla.org/kb/safe-mode-thunderbird

Is problem better? worse?

You can send to my address.

Send.

Thank you, I'll try all suggestions you write above and give needinfo request when I'll post the result.

[Chnutz]

Edit: I use for every cooperation or forum a special mail adress. Some of them are totally useless and generates only spam. So I give yet a forwarding for these mails to the test account :-)

I forget: If you want to compare server and TB content: The webmail-login is https://webmail.all-inkl.com

Comment 6

It needs some more time for all tests, but here the first answers:

- Check Windows task manager - when Thunderbird freezes, is how much CPU and memory are Thunderbird using. And are there any other system processes?
+ CPU 0 - 0.3%, memory av. 140 - 160 MB

- Please measure the number of seconds of freeze
+It's not easy to catch the exact begin of the freeze with looking at the clock and if some more spam appeared, the freeze lasts longer but it seems always be a time around 90 seconds.

- do you have many filters?
+ No filter in TB, only on the server.

- and if you have addressbook whitelisting enabled in Account>Junk Settings, how many contacts in your addresses books
+ 21 personal (whitelist enabled) and av. 500 collected addresses (disabled).

Sorry, it needs some more time for the safe mode test because I'm full of work till 18th of september.

[Wayne Mery (:wsmwk)]

What were your results with safe mode?

Comment 8

[Chnutz]

Sorry, it needs some time to combine spam receiving, time and work ;-)

But now here are the results:

1.) Windows Normal Mode | Thunderbird Normal Mode | Error
2.) Windows Normal Mode | Thunderbird Safe Mode   | Error
3.) Windows Safe Mode   | Thunderbird Normal Mode | Fine
3.) Windows Safe Mode   | Thunderbird Safe Mode   | Not tested

This fits to the fact that Thunderbird with exactly the same settings, accounts and plugins works fine on WIN 7

Comment 9

[Wayne Mery (:wsmwk)]

> 3.) Windows Safe Mode   | Thunderbird Normal Mode | Fine

This suggests that something initialized during Windows startup is causing the problem, and not Thunderbird.  Two common items are Windows indexing, and antivirus software (sometimes disabling AV is not sufficient to stop all its functions).

Comment 10

[Chnutz]

Look at my first report:
" and delete Kaspersky Internet Security (KIS);"

I think when I deleted it complete it was sufficient to stop all its functions ;-)

I'll try it with Indexing.

Comment 11

[Chnutz]

I've tried it with stopping the index completely: no effect
Re-indexing: no effect

By the way: the thunderbird program path and user profile files seemed not target of the indexing in a normal windows 10 system - these places are not checked when I have start to look at it.

Any other idea?

I wondered about why only two programs are affected, Thunderbird and Libre Office.
And Libre Office is only affected when Thunderbird is running.

That's the reason why I'm thinking that it's not a prevailing windows problem, more a thunderbird issue.

That is correct, normally it is not.

no idea what's going on. But if comment 8 #3 is correct, then the problem is not Thunderbird.
