http://www.slony.info/bugzilla/show_bug.cgi?id=80 Summary: slon daemon restarts itself in a loop after failover() Product: Slony-I Version: 1.2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: medium Component: core scripts AssignedTo: slony1-bugs at lists.slony.info ReportedBy: pfote at ypsilon.net CC: slony1-bugs at lists.slony.info Estimated Hours: 0.0 Created an attachment (id=31) --> (http://www.slony.info/bugzilla/attachment.cgi?id=31) log and slonik scripts when dropping the "failed" node immediately after the failover() command, it might happen that a node gets the dropNode_int() command while the failed node is still referenced in the sl_set table. the dropNode_int() then fails because the foreign key contraint "set_origin-no_id-ref" fails. The slon deamon then restarts itself and tries again to drop the node (which fails) and restarts itself in a endless loop, rendering the node unusable; If you wait a bit after the failover() before dropping the node, everything works fine. attached are the slonik scripts to setup the test and to (hopefully) reproduce the problem, and some of the slon daemon log of the node that went wild. The setup was as follow: 4 nodes 1-4, 1 as master, 2-4 as slaves directly subscribing on the master. then the master is assumed to be broken and 4 should become the new master, so nodes 2 and 3 are re-subscribed to node 4, then the failover is executed, waited and then the "failed" old master dropped. i have to apologize i forgot to switch languages on me dev machine so some of the error messages in the slon log are in german.
