805405 - Memory leak after LAN unplugged (Thunderbird 16.0.1, Lightning 1.8, Provider for Google Calendar 0.17)

Status: RESOLVED WORKSFORME

(Calendar :: Provider: GData, defect)

Description

[0h]

User Agent: Opera/9.80 (Windows NT 5.1; U; en-GB) Presto/2.10.289 Version/12.02

Steps to reproduce:

I'm running Thunderbird with "Events ant Task" panel opened. Several times I've noticed Thunderbird allocated about 800 MB of the memory (normal size for my system is around 200 MB) and everything hangs. It only happens if Provider for Google Calendar is enabled and I noticed it after last update. I have 9 calendars: 1 from Exchange (using DavMail), 7 from Google, and 1 from local file.

After some investigation I've got following procedure to reproduce the problem:
1. Run Thunderbird.
2. Wait list of events appear.
3. Unplug the LAN cable.
4. Wait until next update of the events list.


Actual results:

One of two processor cores starts to work on 100% and memory usage start growing. Reconnecting the LAN cable doesn't help.


Expected results:

Nothing / warning.

There has been a major rewrite of the Provider for Google Calendar between version 0.32 and 1.0. A vast number of bugs have been fixed during this rewrite, therefore I am closing lots of old bugs that I think might either be fixed or no longer apply to the latest version.

Please read the updated FAQ [1] for details on known issues. If you can reproduce your issue with the latest version of the Provider for Google Calendar and you can't find an existing bug that handles your case, please reopen this issue.

Thank you for your understanding.
