Hello, I am having an issue using stgt as my iSCSI target. It works with great performance most of the time, however, twice in two weeks it locked up. The first time we lost complete system responsiveness, so did not notice it was stgt. This time we caught it, saw it was at 100% CPU, the VMs (we are using the target for esxi) were unresponsive. Backups were being taken on the VMs, so there would have been unusually high IO during this time. Logs during/after the lockup: messages:Aug 26 03:12:51 linuxiscsi tgtd: abort_task_set(1096) found 8bf8aa5 0 messages:Aug 26 03:12:51 linuxiscsi tgtd: conn_close(100) connection closed, 0x9a0a238 32 messages:Aug 26 03:12:51 linuxiscsi tgtd: conn_close(106) sesson 0x9a0a4a0 1 messages:Aug 26 03:12:51 linuxiscsi tgtd: conn_close(163) Forcing release of tx task 0x9a9f210 8bf8a91 messages:Aug 26 03:12:54 linuxiscsi kernel: tgtd[3171]: segfault at 0000000009a9f280 rip 00000000004070b3 rsp 00007fff4381af70 error 6 messages:Aug 26 03:12:54 linuxiscsi tgtd: tgtd logger exits abnormally, pid:3172 messages:Aug 26 04:26:42 linuxiscsi tgtd: iser transport register messages:Aug 26 04:26:43 linuxiscsi tgtd: tgtd daemon started, pid:23014 messages:Aug 26 04:26:43 linuxiscsi tgtd: tgtd logger started, pid:23016 debug:0 messages:Aug 26 04:26:44 linuxiscsi tgtd: bs_init(318) use pthread notification [root at linuxiscsi log]# tgtadm --op show --mode target Target 1: iqn.2008-09.com.server:server.target1 System information: Driver: iscsi State: ready I_T nexus information: I_T nexus: 1 Initiator: iqn.1998-01.com.vmware:esxiphost1-06680a2b Connection: 0 IP Address: 172.24.34.71 LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB Online: Yes Removable media: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: IET 00010001 SCSI SN: beaf11 Size: 1005894 MB Online: Yes Removable media: No Backing store type: rdwr Backing store path: /dev/cciss/c0d0p4 Backing store flags: Account information: ACL information: ALL Any information or pointers would be very helpful.
