RPM versions: rgmanager-debuginfo-1.9.78-1 rgmanager-1.9.78-1 magma-debuginfo-1.0.8-1 magma-1.0.8-1 magma-plugins-1.0.14-1 magma-plugins-debuginfo-1.0.14-1 magma-devel-1.0.8-1 gulm-devel-1.0.10-0 gulm-1.0.10-0 gulm-debuginfo-1.0.10-0 So, this is a bug in gulm which I think is affecting rgmanager. If you kill a process which has a gulm lock, the lock is never released. Note: it may be a "works as intended" method of operation to support lock failover. I'm looking at the gulm code to see if Slave-side caching of locks is done by-connection (I expect it is, but I don't know). If so, I am contemplating making a patch to gulm which will allow locks to be dropped if the connection from Slave->client (on the same host) or Master->client (on the same host) dies. The reason we can't do client->Master (on a different host) is because failover of support of the masters requires the ability to reconnect as-needed. This bugzilla has Keywords: Regression. Since no regressions are allowed between releases, it is also being proposed as a blocker for this release. Please resolve ASAP. Modified. As it turns out, this bugzilla was due to an incorrect unlock check in rgmanager; a two-line patch fixes it. Gulm does hold locks open even if the process dies, but I do not believe this is a bug - rather, I believe this is a "works as intended". Fix verified in rgmanager-1.9.80-1. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
