So I went as far as the following: - compare the configuration: they only differ in the hostnames as expetd - compare the output of the JMX JGroups' attribute-values with a diff tool. A few numbers are different... but I do not think that this is important.
I then finally activated debug using logback.xml and reproduced the very simple: - create doc Sandbox.A on node 1 - verify it is visible in node 2 - edit it there (e.g. adding a letter in the title), save - fail to see the changed title in node 1 As I indicated by the "dissymetric" subject of the mail: in our two pairs of clustered servers, this only happens when node 1 and node 2 are very precise machines and it does not happen if you exchange machine 1 and machine 2. In the log I saw that the message was received but, apparently, something prevented that arrival from actually happening. What could prevent this arrival to propagate? thanks in adnvance Le 18 sept. 2012 à 19:30, Joshua Marks a écrit : > Also any input on how to debug is greatly appreciated. > -----Original Message----- > Paul Libbrecht > To: XWiki Developers > Subject: [xwiki-devs] dyssmetric cluster... what's up? > > > Hello devs, > > we are having a very very weird bug: the two nodes of our cluster are made > of A and B and saved objects sync into B when written on A but fail to do > sync into A when written on B. > > What could be the cause? > > thanks in advance _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
