859176 - Lightning leaks threads

Status: RESOLVED DUPLICATE of bug 833720

(Calendar :: General, defect)

Description

[Jeff Siddall]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/20130308 Firefox/17.0
Build ID: 20130220111618

Steps to reproduce:

Open a network calendar.  I currently have one WebDAV server hosting a shared calendar as well as a few readonly calendars on the internet.


Actual results:

Thunderbird begins spawning threads at a rate of approx. 100 per day.  All thunderbird operations (including email) get slower over time until eventually some limit is hit and the OS stops handing out process.  The application must be restarted to get things back to normal.


Expected results:

Thunderbird uses a few threads and << 1 GB RAM.  Here is the current thunderbird info after running for about 5 days:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
20599 siddall   20   0 7934m 1.4g  20m S 99.0 19.4 217:33.15 thunderbird

Running:
ps -eLf | grep bird | grep siddall | wc -l

returns:
538

OS is Scientific Linux 6.3, Thunderbird is 17.0.3 but this problem has existed for at least a year on many previous versions.

In case it is important, thunderbird is behind an HTTP proxy.

Problem is already solved in Lightning 2.2 beta and scheduled for the 1.9.2 bugfix release.
