[uml-devel] do_syscall_stub: syscall 9 failed

[uml-devel] do_syscall_stub: syscall 9 failed

[Antoine Martin]

Just caught this in `dmesg`

[42977596.520000] Adding 131064k swap on /dev/ubdb.  Priority:-1 
extents:1 across:131064k
[42980169.290000] do_syscall_stub : ret = -12, offset = 548682067984, 
data = 0000000060b16010
[42980169.290000] do_syscall_stub: syscall 9 failed, return value = 
0xfffffffffffffff4, expected return value = 0x477a000

[42980169.290000] fix_range_common: failed, killing current process

Whilst trying to compile gcc (big beast) on a 64-bit UML instance.
Earlier it had failed and triggered OOM, which is why I added the swap, 
now it may still not have enough (compilation crashed in a similar 
manner) but this time there is no OOM message.

Any ideas what this is?

Cheers
Antoine

It is 100% reproducible now, here is the gcc compilation output:

Sounds like it might be the host /proc/sys/vm/max_map_countbeing
exceeded, which will happen with a UML process with 256M RSS.

Indeed it was (never heard of it before)

Thanks!
