Re: [Ganglia-general] Ganglia 3.3.1 on RHEL6 - unable to create tcp_accept_channel

2012-02-16 Thread Ramon Bastiaans
I have the same problem with 3.3.1 (on Debian) with no udp_receive_channel set in the config. Which is how we used to do it. When I add the udp_receive_channel it works, but I don't want the daemon to listen. As a workaround I have now set the daemon to be "deaf", which seems to work. But it

Argh, I hate breaking the threading but my mailbox seems to have eaten a bunch of the messages in the thread! Mark, your patch does the trick, and that makes sense since most of these systems do not have udp_receive_channels set. They are just collecting stats and forwarding them off to a cent

Do you have any udp_receive_channels defined? Between 3.1.1 and 3.3.1 the variable "udp_last_heard" was introduced. From just looking at the source (no experimentation) I'm guessing this is what is happening: The function setup_listen_channels_pollset(0) sets up the listening tcp socket. Since

Weird, I'm seeing it on two different machines (all that we've installed it on at this point). Both installed with the same RPM. The RPM was built by simply extracting the spec file from the source tarball and running rpmbuild -ba on it. This is running on RHEL 6.2 just reinstalled last Wed (o

I have been testing 3.3.1 on RHEL6 and I haven't seen this issue. I actually kicked off a new VM just now, built RPMS from scratch and it's working correctly. Vladimir On Thu, 9 Feb 2012, drich wrote: I am starting to test Ganglia 3.3.1 on RedHat Enterprise 6, but have run into a problem.
