problem on bgp session

[LukeCage]

hello,

tnsr closing my peer connection i get log on remote device

What could this problem be caused by? I don't think there is an error in the configuration.

note: i run packet sniffer, capture packets of BGP session

i see then keepalive messages and at one point tnsr with IP 10.62.40.245 sends TCP FIN and closes connection without any obvious reason
