Re: [Ganglia-developers] gmetad dies when it is cleaning itself.

[Bernard Li <be...@va...>]

Hi Miguel:

Perhaps you can post the debug log snippets showing us where gmetad
dies.  How reproducible is the crash?  You might want to run gmetad
via gdb to see if you can get a backtrace.

Also, how's the load on the system?  Are you experience high disk I/O?
 If you are monitoring a lot of metrics you might consider setting up
rrdcached.

P.S. Please also post the OS and architecture you're running gmetad server on.

Cheers,

Bernard
