the iouyap exit error [iouyap.c:main:1170: PID 1520 already has a lock on ID 514]

[superwolfboy]

When I add the second iou instance the message console on Gns3 1.1 pops up

=> Server notification: node IOU2: iouyap has stopped running
iouyap.c:main:1170: PID 1520 already has a lock on ID 514

the iou is running in Gns3 iou vm .

how to fix it ?
thank you !

In the last gns3 I didn't see this , maybe this issue should be closed.
thank you ~
