Description

[murphy.zhao]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36

Steps to reproduce:

did nothing, but start it, then it froze there after 1 miniute more or less


Actual results:

it just pop up one window message
  “Sent Items - Mozilla Thunderbird” is not responding.
  You may choose to wait a short while for it to continue or force the application to quit entirely"
then, it seems froze there for ever.

And the cpu usage was checked, almost 100% in one cpu.
Also strace the process with much much error like this:
  futex(0x7ff538200040, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)



Expected results:

expect it work normal

Which version of Thunderbird?
Which flavor of linux?
Does it also happen in safe mode?

Hi,

It seems to work when started in safe mode and the add-on/extension has been checked, there is only one extension callled lightning.

It's a little weird that after that once safe-mode startup, I started the thunderbird as normal, without change anything, the issue just gone. Anyway, thanks for this suggestion. Please let me know if you still would like to debug more information.

Regards,

Safe mode has been  known to do that.  One theory is it is a result of disabling the JIT compiler - https://en.wikipedia.org/wiki/SpiderMonkey

Apparently you are  not using the calendar functions??

Didn't ever use it, but I see there is one "Calendar" folder in the left sidebar and some appointment emails there. Guess the function automatically enabled once the appointment email received.

Not much knowledge about the JIT compiler, but as reference to the strace output, it seemed like one polling issue with futex checking and returning immediately with error.
  "futex(0x7ff538200040, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)"

Likely a duplicate of bug 1265242

Same problem here.
Since a few days Thunderbird will freeze when started.
I have only one addon installed (Lightning) and if I disable it via safe-mode, Thunderbird will start normally again.

I think the problem was introduced in one of the two last updates of Lightning.

Also for interactions with any add-ons, FB/FF/etc. must not block. 
The calling Mozilla (core?) component should add some timeout mechanism (for instance by spawning a thread) in order to protect the rest of the application from freezing.

murphy, so you are currently unable to reproduce, is that correct?

It's hard to tell from comment 0, but it sounds like "Unresponsive Script"

Yeah, after your suggested safe-mode restart, the unresponsive issue didn't show up now. 
This issue happened both on my PC and laptop. I'll re-install my laptop this weekend, will check if this issue could be reproduced. Will keep you posted if it happens again.
