https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217239 --- Comment #6 from Mark Millard <markmi@dsl-only.net> --- It turns out that for the script and powerd examples the whole tsd->tcache[0] through tsd->tcache[40] area (__je_nhbins=3D=3D41) is all zeros. That includes the lg_fill_div members of each. For the su examples there is a next_gc_bin in tsd->tcache[2] that is non-zero: print/x tsd->tcache[2] (lldb) print/x tsd->tcache[2] (tcache_t) $1 =3D { link =3D { qre_next =3D 0x0000000000000000 qre_prev =3D 0x0000000000000000 } prof_accumbytes =3D 0x0000000000000000 gc_ticker =3D (tick =3D 0x00000000, nticks =3D 0x00000000) next_gc_bin =3D 0xffffffff tbins =3D { [0] =3D { tstats =3D (nrequests =3D 0x0000000000000000) low_water =3D 0x00000000 lg_fill_div =3D 0x00000000 ncached =3D 0x00000000 avail =3D 0x0000000000000000 } } } But the rest of the tsd->tcache area is zero. --=20 You are receiving this mail because: You are the assignee for the bug.=
