Hello experts,
I am using a Northbound client to access the Opendaylight SDN
Controller (ODL) RESTful api which uses JAX-RS javax.ws.rs v2.0 and its
implementation Jersey API v1.17.
When a device connects, ODL exposes the REST services through port
8443. Thus, on startup the Northbound client tries to access the device
using RESTConf at port 8443.
I have many ~50 devices that come up. The socket count for port 8443
increases and when it reaches ~90 the devices are brought down. This
ends up in many 8443 sockets in CLOSE_WAIT state on the ODL (server)
side.
Is there any outstanding issue/bug for Jersey or javax.ws.rs closing
the connections that could possibly explain these CLOSE-WAIT sockets?
More context:
[1]: Resource class and method definition. The PUT REST service is
where I see the issue.
[2]: REST Service implementation for PUT request, where the Response
object is returned.
I would appreciate any leads that would help me with this issue. Please
let me know if you need me to add more information.
