Hi,there! By modifying the weight value of the routing attribute through the filter, the system becomes extremely sluggish, with bird consuming nearly 100% of the CPU. OS： Alpine Linux 3.23 bird version: 2.18 filter code: function xxx() {     if (1, 1, 200)~ bgp_large_community then { bgp_med = bgp_med + 500; weight = 10;     }     if (1, 1, 197)~ bgp_large_community then { bgp_med = bgp_med + 505; weight = 20;     } } system log: Jan 10 00:03:19 r1 daemon.warn bird: I/O loop cycle took 30216.832 ms for 22 events Jan 10 00:03:38 r1 daemon.warn bird: I/O loop cycle took 18453.030 ms for 23 events Jan 10 00:03:56 r1 daemon.warn bird: I/O loop cycle took 18454.469 ms for 14 events Jan 10 00:04:15 r1 daemon.warn bird: I/O loop cycle took 18441.226 ms for 13 events Thank you
