It's a merge of captures of two target SAN interfaces (10.22.1.208, 10.22.2.208). The deadlock occured in 18:57:17 CET. I guess it was caused by packets 5979 and 5980: 5979 62.915577 10.22.102.66 10.22.1.208 iSCSI 126 SCSI: Persistent Reserve Out LUN: 0x01 SCSI: Data Out LUN: 0x01 (Persistent Reserve Out Request Data) 5980 62.915722 10.22.102.52 10.22.2.208 iSCSI 126 SCSI: Persistent Reserve Out LUN: 0x01 SCSI: Data Out LUN: 0x01 (Persistent Reserve Out Request Data) Martin
