Dear OpenBGPD Community,
in order of measuring the performance of OpenBGPD I need to connect it with a huge amount of peers (realized by ExaBGP). OpenBGPD 5.8 works well with 100 Peers but if I increase that number to 250 I got every try the same error (debug mode): handle_pollfd: imsg_read error: Resource temporarily unavailable SE: Lost connection to RDE handle_pollfd: poll fd: Undefined error: 0 RDE: Lost connection to SE handle_pollfd: poll fd: Undefined error: 0 RDE: Lost connection to SE control handle_pollfd: poll fd: No such file or directory main: Lost connection to SE route decision engine exiting Segmentation fault (core dumped) I guess its caused by the big number of peers or the short time interval they connect. I also checked 5.7 but same behavior with slightly other error msgs: fatal in SE: session_dispatch_imsg: imsg_read error: Resource temporarily unavailable Lost child: session engine exited fatal in RDE: rde_dispatch_imsg_session: pipe closed Lost child: route decision engine exited Terminating If I split the Peers to 100, 50, 100 with 10 Seconds pause between arrival, OpenBGPD breaks with same error when the 50 Peers are changing to established. Would be nice if you can help me. Regards, Daniel Seidenstuecker
