Error description
Multiple clients making simultaneous request to resource-manager statistics can lead to the integration server abend. The typical abend stack seen in such situation is : _ZN19ImbOdbcStatsManager16reportStatistics _ZNK18ImbResourceManager22getLiveStateStatistics _ZNK18ImbResourceManager12getLiveState _ZNK18ImbDatabaseManager12getLiveState _ZN18ImbAdminRESTHelper43populateConfigObject The resource manager stats request is of following form : curl -X GET http://{host:port}/apiv2/servers/{IS}/resource-managers?depth=2 The ACE Toolkit also makes similar REST Admin query when establishing connection with Int Node. So if multiple Toolkits try to connect to same Integration Node, it can lead to Integration Server abend.
