[Crash-utility] WARNING: malloc/free mismatch

Hello, Today while I was looking into a vmcore, I got suddenly the message in $SUBJECT. It started after I did a search into the process stack pages (search -t) and for each command I run afterwards I kept getting that message. For example: $ retrace-server-interact 603967269 crash ... crash> search -t ffff88040a0d5280 search: invalid list entry: 0 search: invalid list entry: 0 search: invalid list entry: 0 PID: 606 TASK: ffff88082d226eb0 CPU: 5 COMMAND: "xfsaild/dm-0" ffff88083ff5b948: ffff88040a0d5280 ffff88083ff5b990: ffff88040a0d5280 ffff88083ff5baa8: ffff88040a0d5280 ffff88083ff5baf0: ffff88040a0d5280 ffff88083ff5bcf0: ffff88040a0d5280 ffff88083ff5bd38: ffff88040a0d5280 ffff88083ff5bd98: ffff88040a0d5280 WARNING: malloc/free mismatch (29/32) crash> ps -m | grep UN [ 0 00:00:00.146] [UN] PID: 1811 TASK: ffff880c17bd1fa0 CPU: 1 COMMAND: "cp" WARNING: malloc/free mismatch (29/32) I guess this comes from a possible corrupted vmcore (I just got it from this vmcore), but I wonder why every new command keeps returning the same message. Thanks, Pier
