Hello bird community, I upgraded on of our VIX Routeservers from 1.5 to 1.6 recently. When running 1.6 I receive a lot of loglines: ------- May 19 07:33:10 rs1 bird: Pipe loop detected when sending x.y.z.a/b to table Tcxd root@rs1:/var/log# grep "Pipe loop detected" daemon.log | wc -l 1914110 root@rs1:/var/log# ------- (log rotated on a daily base) I guess there exists a kind of race condition when accessing the table for updating. Running 1.5 I didn't find a single line like those. Config remained the same +/- different prefix-lists, install base is Debian 8.4, .debs from bird.network.cz/debian/ any hints? Thank you best regards Robert -- www.vix.at | www.aco.net robert.wein@univie.ac.at | RW2586-RIPE Vienna University Computer Center Tel: +43 1 4277-14046 | Fax: -14338
