@rafaelweingartner Tried tracing where deadlock 5 originated. It seems
both transactions are part of the same method fetchNewPublicIp in
IpAddressManagerImpl . Transactions are executed on different management
servers.
Update is triggered through markPublicIpAsAllocated method
Select seems to come from there as well fetchNewPublicIp in
IpAddressManagerImpl
AssignIpAddressFromPodVlanSearch =
_ipAddressDao.createSearchBuilder();
AssignIpAddressFromPodVlanSearch.and("dc",
AssignIpAddressFromPodVlanSearch.entity().getDataCenterId(), Op.EQ);
AssignIpAddressFromPodVlanSearch.and("allocated",
AssignIpAddressFromPodVlanSearch.entity().getAllocatedTime(), Op.NULL);
SearchBuilder<VlanVO> podVlanSearch =
_vlanDao.createSearchBuilder();
podVlanSearch.and("type", podVlanSearch.entity().getVlanType(),
Op.EQ);
podVlanSearch.and("networkId",
podVlanSearch.entity().getNetworkId(), Op.EQ);
SearchBuilder<PodVlanMapVO> podVlanMapSB =
_podVlanMapDao.createSearchBuilder();
podVlanMapSB.and("podId", podVlanMapSB.entity().getPodId(), Op.EQ);
AssignIpAddressFromPodVlanSearch.join("podVlanMapSB", podVlanMapSB,
podVlanMapSB.entity().getVlanDbId(),
AssignIpAddressFromPodVlanSearch.entity().getVlanId(),
JoinType.INNER);
AssignIpAddressFromPodVlanSearch.join("vlan", podVlanSearch,
podVlanSearch.entity().getId(),
AssignIpAddressFromPodVlanSearch.entity().getVlanId(), JoinType.INNER);
