This is strange, the problem would happen in heavy forked system which have lots of pages are shared between lots of process and most are commited to these processes, this is a known FreeBSD VM problem, the pv_entry are static allocated using vm_zone with max limit set. strange thing is it happens in booting time. -- David Xu Emiel Kollof wrote: >>From my dmesg: >pmap_collect: collecting pv entries -- suggest increasing PMAP_SHPGPERPROC > >What does that mean?
