Connecting/disconnecting links causes server hang + project won't open

Hey guys,

This is for 2.0.3 running on a remote server.

Occasionally when adding or removing links to various types of devices, the client will timeout trying to connect back to the server and fail. Sometimes requiring a restart of the gns3server. Usually upon restart, the project comes back with the link added or removed as requested.

=> Timeout request http://cin@10.127.49.58:3080/v2/projects/d59e9bb4-751b-4521-b38c-c7214ade1da5/links Error while creating link: Operation timeout

This time however, when the server came back online the project couldn't be opened. The client says "Port already in use" and the client crashes.

Bad request http://10.127.49.58:3080/v2/compute/projects/d59e9bb4-751b-4521-b38c-c7214ade1da5/qemu/nodes { "message": "None is not of type 'integer'\n\nFailed validating 'type' in schema['properties']['console']:\n {'description': 'Console TCP port',\n 'maximum': 65535,\n 'minimum': 1,\n 'type': 'integer'}\n\nOn instance['console']:\n None", "method": "POST", "path": "/v2/compute/projects/{project_id}/qemu/nodes", "request": { "acpi_shutdown": false, "adapter_type": "e1000", "adapters": 16, "bios_image": "", "boot_priority": "c", "cdrom_image": "", "cpu_throttling": 0, "cpus": 1, "hda_disk_image": "vios_l2-adventerprisek9-m.03.2017.qcow2", "hda_disk_image_md5sum": "8f14b50083a14688dec2fc791706bb3e", "hda_disk_interface": "virtio", "hdb_disk_image": "IOSv_startup_config.img", "hdb_disk_image_md5sum": "bc605651c4688276f81fd59dcf5cc786", "hdb_disk_interface": "virtio", "hdc_disk_image": "", "hdc_disk_interface": "ide", "hdd_disk_image": "", "hdd_disk_interface": "ide", "initrd": "", "kernel_command_line": "", "kernel_image": "", "legacy_networking": false, "linked_clone": true, "mac_address": "00:1d:a5:67:eb:00", "options": "-nographic", "process_priority": "normal", "ram": 768, "usage": "" }, "status": 400 }

Here is the project, if that helps:
