Rulez un invitat Ubuntu Server pe o gazdă Windows 10 în Virtualbox.
- 2048 MB Ram (gazda are 32 GB)
- 4 procesoare (gazda are 4 nuclee, 8 fire)
- PAE/NX, VT-x/AMD-V activat
- 128 MB VRAM
- disc VDI de 10 GB
- Adaptor desktop cu punte IntelPRO/1000 MT
Rulez în mare parte rtorrent prin openvpn, descarcând în Windows montate acțiuni smb. folosind apache pentru a comunica între rutorrent și rtorrent. totul funcționează bine până acum, dar mă blochez la fiecare oră și ceva, și de data aceasta am rulat de top și mi-a dat următorul mesaj când s-a prăbușit:
Mesaj de la syslogd@ubuntuserver la 2 iulie 17:01:21...
kernel:[ 7706.657113] usercopy: încercarea de expunere a memoriei kernelului a fost detectată de la obiectul SLUB „vm_area_struct(1985:init.scope)” (offset 45, dimensiunea 187)!
Nu sunt deloc un expert în Linux, așa că orice ajutor ar fi foarte apreciat.
Am căutat în /var/log/kern.log toate aparițiile sau „expunerea”, așa că sperăm că acestea sunt fișierele jurnal relevante:
