Error while setting TS (binding). ERR: Address already in use (3)

[Richard70]

Hi,

from time to time I have issues to start some nodes (here csr1000v 16x). This tends to happen when I try to start manually (selecting them) 3 or 4 nodes at the same time (out of 60).
That can happen even when there are no or very few other nodes running at the same time.
I get in the wrapper file the following logs:
root@eve-ng:/opt/unetlab/tmp/0/577a08b0-6cf3-4e7f-a2ea-b9fd10d1901c/18# more wrapper.txt
8/3 19:13:57.776 INF Tennant_id = 0
8/3 19:13:57.776 INF Device_id = 18
8/3 19:13:57.776 ERR Error while setting TS (binding). ERR: Address already in use (3).
8/3 19:13:57.776 ERR Failed to open TCP socket (3).

If I close the lab and start again, that works.
Tried to search for this error message in the forums, with no luck.
Any idea ?
Thanks.

Hi,
I'm now completely stuck with these nodes , impossible to start them.
I don't have any error log in wrapper.txt anylonger:
root@eve-ng:/opt/unetlab/tmp/0/577a08b0-6cf3-4e7f-a2ea-b9fd10d1901c/18# more wrapper.txt
9/3 17:24:25.809 INF Tennant_id = 0
9/3 17:24:25.809 INF Device_id = 18
9/3 17:24:25.809 INF TS configured.
but the nodes simply do not start.
A fresh added node with the same image works fine.
I would really appreciate help.
Thanks

added note: wrapper logs:

It happens

Community use static ports... means if you have already a linux process using this port -> issue...

Pro use dynamic port (always looking for a free port ) and do not suffer of such situation....
