Hello ,
I encountered the same bug on Nexus 7000 and on ios version 6.2 (12) as nexus 9000 is it the same problem and please help me to know the cause.
Like this example below :
2016 Jan 12 11:15:16 NSW023002-PRD %NETSTACK-3-IP_INTERNAL_ERROR: netstack [8099] Failed to initialise bitfield
2016 Jan 12 11:15:16 NSW023002-PRD %NETSTACK-3-IP_INTERNAL_ERROR: netstack [8099] -Traceback: 0x80a6bb5 0x80a72d7 0x80b87db librsw.so+0xaa81f libpthread.so.0+0x6140 libc.so.6+0xcedee
best regards .
