When we=E2=80=99re at rust and memory (thread-local storage?) related: =
I=E2=80=99ve tried to run databases/qdrant
in production. It works until it=E2=80=99s idle. When some collections =
are being created/loaded, it crashes.
I have been able to track it down to malloc() called from within =
strdup() called from within thr_set_name().
That internally calls, something like:
frame #6: 0x00003f6e7cbc8955 =
libc.so.7`__je_tsd_fetch_slow(tsd=3D0x00003f6faeb53090, =
minimal=3D<unavailable>) at jemalloc_tsd.c:0
frame #7: 0x00003f6e7cb77e3a libc.so.7`__je_malloc_default [inlined] =
tsd_fetch_impl(init=3Dtrue, minimal=3Dfalse) at tsd.h:355:10
frame #8: 0x00003f6e7cb77e30 libc.so.7`__je_malloc_default [inlined] =
tsd_fetch at tsd.h:381:9
frame #9: 0x00003f6e7cb77e30 libc.so.7`__je_malloc_default [inlined] =
imalloc(sopts=3D<unavailable>, dopts=3D<unavailable>) at =
jemalloc_jemalloc.c:2256:15
frame #10: 0x00003f6e7cb77e30 libc.so.7`__je_malloc_default(size=3D40)=
at jemalloc_jemalloc.c:2293:2
I can reliably reproduce the problem on both stable/13, stable/14 and =
main.
