Hi,
I noticed that many systems registered with my Spacewalk 2.6 server
become offline from time to time. This means that I cannot update them
in real-time. They sometimes stop being offline if I perform some
restarts including whole spacewalk server, but it doesn't always solve
this problem. I dig into OSAD logs on some of the clients that are
offline and I found out that they communicate with the main jabberd
server/osa dispatcher, but the they are not being set as online.
I only noticed that on the faulty nodes in the callback response there
is subscription='to' not the subscription='both', like it is on the
working nodes. I read somewhere that it should to be set to "both", but
I am not an expert :(

As you can see this request is sent repeatedly almost every 10 seconds
and host don't become online. Also I can see that the there are some
logs regarding this client in osa-dispatcher logfile.
What can be an issue here ? Is Jabber blocking some types of connections
or maybe there is an issue with sqllite db ? or even with spacewalk db ?
Because this problem is not persistent, like I said with some restarts
some of the nodes become online.
Kind regards,
Piotr Dzionek
