Hi, When we run Soapaligner application( http://soap.genomics.org.cn/soapaligner.html#down2) on LXC/LINUX-CR ( https://ckpt.wiki.kernel.org/index.php/Link-LXC-USERCR#Checkpoint.2Frestart_a_simple_LXC_container), we use lxc-checkpoint to try to create a checkpoint of the running process, at that time the application crashed, here's the system event log(/var/log/message) Mar 14 13:16:41 ip-10-98-14-121 kernel: rr:325]_pgarr:325] go_pgarr:32_pgarr:32_pgarr:325] _pgarr:32_pgarr:325]
