[Pkg-monitoring-maintainers] Bug#737960: ganglia-monitor: gmond segfault

[Markus Koeberl]

Package: ganglia-monitor
Version: 3.6.0-2
Severity: normal

Dear Maintainer,
I am replacing an old ganglia setup running on debian lenny which consists of  4 clusters. Therefore I changed the init.d script to run 4 instances of gmond. I also configured it to use rrdcached. The main difference to the old setup is that I activated sFlow support and that I changed from tmpfs to rrdcached. I changed the configuration of the clients to send to both the old and the new server.

During the last Day I got 3 segfaults:

Feb  6 09:53:52 web05 kernel: [232710.661591] gmond[24775]: segfault at cc000928 ip 00007f6ad56f2f21 sp 00007f6ad2a9bfb8 error 4 in libc-2.13.so[7f6ad5672000+182000]

All 3 segfaults could be related to sFlow. I configured sFlow on some Windows hosts. It is possible that the segfaults occurred when a Windows host is booted bat I am not completely sure about that.
