[j-nsp] Junos Telemetry no port numbers include in packets

[Martyniak Lukasz]

Hi All

I have a question in junos telemetry. I have some MX telemetry streams  with does not include the ports number into UPP packages 
Other MX is working fine (both have same hardware, software version 16.2R2.8 - mx104 and analytics config)
Do any of you have similar issues ? Any know solution ?

tcpdump on the collector server :

from MX1 :
13:59:42.663324 IP (tos 0xc0, ttl 252, id 1532, offset 0, flags [none], proto UDP (17), length 1232)
    10.200.10.3.1000 > 10.200.10.10.50000: [no cksum] UDP, length 1204

from MX2: 

13:46:48.141313 IP (tos 0xc0, ttl 254, id 1509, offset 1760, flags [none], proto UDP (17), length 1309)
    10.200.10.2 > 10.200.10.10: ip-proto-17
