https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276870 --- Comment #6 from Borja Marcos <borjam@sarenet.es> --- I may have something related (or not). I have observed a severe mbuf leak with the following sysctl variables grow= ing steadily. vm.uma.mbuf_packet.stats.current vm.uma.mbuf_cluster.stats.current vm.uma.mbuf.stats.current THe server on which I have been observing this runs quite a lot of stuff, s= o, suspecting some particular process(es) causing this I checked for the culpr= it. Turns out the culprit (trigger I should say) is a version of nfsen that uses threads. My main suspects are the nfcapd or sfcapd daemons which create and destroy threads. The funny thing is, I run two concurrent versions of these daemons. The old ones do *not* leak mbufs, while the recent ones do. The daemons are supposed to be pretty straightforward, receiving UDP packet= s in Netflow/sFlow/IPFix format. --=20 You are receiving this mail because: You are the assignee for the bug.=
