I run trinity within a user mode linux image (latest git kernel). The directory for victims files is located at a NFS mounted share. What I get sometimes when running 4 trinity childrens in parallel is something like the following : 2013-04-26T19:25:29.241+02:00 trinity kernel: INFO: task trinity-child1:1580 blocked for more than 120 seconds. 2013-04-26T19:25:29.241+02:00 trinity kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. 2013-04-26T19:25:29.241+02:00 trinity kernel: trinity-child1 D 001000ce 0 1580 1569 0x00000002 2013-04-26T19:25:29.241+02:00 trinity kernel: 4088902c 00000001 00000000 3b9f7cac 0806198f 3bad786c 4088902c 3b9f4000 2013-04-26T19:25:29.241+02:00 trinity kernel: 080a5290 3b9f7cd8 0837420c 3bad73c0 40888b80 00000001 40585530 3dc54660 2013-04-26T19:25:29.241+02:00 trinity kernel: 3b9f4000 40585610 3bad73c0 ffffffff 3b9f7cec 083742a5 3b9f7de0 00000001 3b9f7c98: [<0806198f>] __switch_to+0x5f/0x100 2013-04-26T19:25:29.241+02:00 trinity kernel: 3b9f7cb0: [<0837420c>] __schedule+0x2dc/0x320 2013-04-26T19:25:29.241+02:00 trinity kernel: 3b9f7cdc: [<083742a5>] schedule+0x55/0x60 2013-04-26T19:25:29.241+02:00 trinity kernel: 3b9f7cf0: [<083742b8>] schedule_preempt_disabled+0x8/0x10 2013-04-26T19:25:29.241+02:00 trinity kernel: 3b9f7cf8: [<083736b3>] __mutex_lock_slowpath+0x63/0x90 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7d20: [<083736fe>] mutex_lock+0x1e/0x30 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7d2c: [<0810928c>] do_last+0x23c/0xd30 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7db8: [<08109e1f>] path_openat+0x9f/0x450 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7e0c: [<0810a201>] do_filp_open+0x31/0x80 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7e7c: [<081026e8>] sys_uselib+0x48/0x150 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7eac: [<08064a92>] handle_syscall+0x82/0xb0 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7ef4: [<08076f2d>] userspace+0x46d/0x590 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7fec: [<080617fc>] fork_handler+0x6c/0x70 2013-04-26T19:25:29.256+02:00 trinity kernel: 3b9f7ffc: [<09e47c20>] 0x9e47c20 2013-04-26T19:25:29.256+02:00 trinity kernel: 2013-04-26T19:25:29.262+02:00 trinity kernel: INFO: task trinity-child0:1609 blocked for more than 120 seconds. 2013-04-26T19:25:29.262+02:00 trinity kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. 2013-04-26T19:25:29.262+02:00 trinity kernel: trinity-child0 D 001000ce 0 1609 1569 0x00000002 2013-04-26T19:25:29.262+02:00 trinity kernel: 409b902c 00000001 00000000 115f7db8 0806198f 409bacec 409b902c 115f4000 2013-04-26T19:25:29.262+02:00 trinity kernel: 080a5290 115f7de4 0837420c 409ba840 409b8b80 00000001 0844cb4c 115f7e00 2013-04-26T19:25:29.262+02:00 trinity kernel: 115f4000 40585610 409ba840 ffffffff 115f7df8 083742a5 00000000 115f7e14 115f7da4: [<0806198f>] __switch_to+0x5f/0x100 2013-04-26T19:25:29.262+02:00 trinity kernel: 115f7dbc: [<0837420c>] __schedule+0x2dc/0x320 2013-04-26T19:25:29.262+02:00 trinity kernel: 115f7de8: [<083742a5>] schedule+0x55/0x60 2013-04-26T19:25:29.262+02:00 trinity kernel: 115f7dfc: [<083742b8>] schedule_preempt_disabled+0x8/0x10 2013-04-26T19:25:29.262+02:00 trinity kernel: 115f7e04: [<083736b3>] __mutex_lock_slowpath+0x63/0x90 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7e2c: [<083736fe>] mutex_lock+0x1e/0x30 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7e38: [<080fb952>] chown_common.isra.18+0x52/0x80 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7e84: [<080fc862>] sys_fchown+0x62/0xc0 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7eac: [<08064a92>] handle_syscall+0x82/0xb0 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7ef4: [<08076f2d>] userspace+0x46d/0x590 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7fec: [<080617fc>] fork_handler+0x6c/0x70 2013-04-26T19:25:29.266+02:00 trinity kernel: 115f7ffc: [<00000000>] 0x0 2013-04-26T19:25:29.266+02:00 trinity kernel: Does those log message contains something interesting for you ? -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
