[Pkg-xfce-devel] Bug#417903: xfce4-weather-plugin: spontaneous CPU consumption after a while

Thu Apr 5 12:11:11 UTC 2007

Package: xfce4-weather-plugin
Version: 0.5.99.1-2
Severity: important

xfce4-weather-plugin seems to work perfectly. However, after some time (several
days to a week?) it starts to use all available CPU time. I've strace'd the
process, and it seems to be stuck in this loop without waiting for anything:

gettimeofday({1175770003, 410099}, NULL) = 0
poll([{fd=3, events=POLLIN}], 1, 0)     = 0
recv(6, 0xbfd41a7c, 1023, 0)            = -1 EAGAIN (Resource temporarily unavailable)
recv(7, 0xbfd41a7c, 1023, 0)            = -1 EAGAIN (Resource temporarily unavailable)
recv(9, 0xbfd41a7c, 1023, 0)            = -1 EAGAIN (Resource temporarily unavailable)
recv(11, 0xbfd41a7c, 1023, 0)           = -1 EAGAIN (Resource temporarily unavailable)
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1175770003, 410255}, NULL) = 0
poll([{fd=3, events=POLLIN}], 1, 0)     = 0
recv(6, 0xbfd41a7c, 1023, 0)            = -1 EAGAIN (Resource temporarily unavailable)
recv(7, 0xbfd41a7c, 1023, 0)            = -1 EAGAIN (Resource temporarily unavailable)
recv(9, 0xbfd41a7c, 1023, 0)            = -1 EAGAIN (Resource temporarily unavailable)
recv(11, 0xbfd41a7c, 1023, 0)           = -1 EAGAIN (Resource temporarily unavailable)
ioctl(3, FIONREAD, [0])                 = 0

The only way I've found to stop this is removing the pluging and re-adding and
re-configuring it. It then works normally for another couple of days, and
starts eating CPU again. Changing options or looking at the weather forecast
doesn't seem to influence anything (everything looks normal BTW).

I only noticed this because I also use a CPU monitor plugin. The system
responds normally, so without looking at monitoring tools the problem may
remain unnoticed.
