Hi We are using RHEL kernel versions (3.10.0-514.41.1, 3.10.0-693.el7.x86_64)
On 3.10.0-514 we are getting a "Soft Lock" Issue while using TIPC in two node cluster. The same issue is not occurring in 3.10.0-693. Information in RHEL errata does not seem to specifically address this issue. Will appreciate if someone can provide any information as to what is causing the issue in 3.10.0-514. Following is the backtrace. : [<ffffffff8155e724>] ? consume_skb+0x34/0x80 : [<ffffffff8156f1f1>] dev_hard_start_xmit+0x171/0x3b0 : [<ffffffff81596864>] sch_direct_xmit+0x104/0x200 : [<ffffffff81571dec>] __dev_queue_xmit+0x23c/0x570 : [<ffffffff81572130>] dev_queue_xmit+0x10/0x20 : [<ffffffffa02c1e46>] send_msg+0xc6/0xf0 [tipc] : [<ffffffffa02b5d14>] tipc_link_send_proto_msg+0x464/0x500 [tipc] : [<ffffffffa02b6330>] ? link_start+0x40/0x40 [tipc] : [<ffffffffa02b6104>] link_state_event+0x354/0x540 [tipc] : [<ffffffffa02b639d>] link_timeout+0x6d/0x160 [tipc] : [<ffffffff81095b46>] call_timer_fn+0x36/0x110 : [<ffffffffa02b6330>] ? link_start+0x40/0x40 [tipc] : [<ffffffff81098837>] run_timer_softirq+0x237/0x340 : [<ffffffff8108f2cf>] __do_softirq+0xef/0x280 : [<ffffffff8169849c>] call_softirq+0x1c/0x30 : [<ffffffff8102d365>] do_softirq+0x65/0xa0 : [<ffffffff8108f665>] irq_exit+0x115/0x120 : [<ffffffff81699115>] smp_apic_timer_interrupt+0x45/0x60 : [<ffffffff8169765d>] apic_timer_interrupt+0x6d/0x80 : <EOI> # cat /var/log/messages | grep "soft lock" kernel: NMI watchdog: BUG: soft lockup - CPU#2 stuck for 23s!
