It looks your host2 has normal value of mbuf usage. Is there the difference of apprication with these hosts? I'm using net-snmp and mrtg to collect statistics of mbuf/mbufc usage. If you can find any trends (increasing at specific time period or so), it would be help for further debugging. ---- mrtg.cfg Target[mbuf]:hrStorageUsed.1&hrStorageUsed.4:public@server MaxBytes1[mbuf]: 40960 MaxBytes2[mbuf]: 20480 Options[mbuf]: gauge,nopercent,growright Title[mbuf]: Number of mbufs in use YLegend[mbuf]: mbufs ShortLegend[mbuf]:   LegendI[mbuf]:   mbufs in use LegendO[mbuf]:   mbuf clusters in use PageTop[mbuf]:
