I re-compile the kernel with opening "HUGHMEM" to let my Linux to support 16GB memory, and it seems to run well under new kernel at the beginning, however, even no operating on this server(for about 18 hours), it meets kernel panic:
kernel panic -not syncing : out of memory and no killable processes
I am using rootfs to run all in memory. I google for this error message and find few suggestions. If it is proved that hugemem is not stable for my current system, I have to build a fresh 64 bit system.
Would you give me any hint for fixing the kernel panic?
Any suggestion would be appreciated.
Here's some options in .config file:
# Firmware Drivers
# CONFIG_EDD is not set
# CONFIG_DELL_RBU is not set
# CONFIG_DCDBAS is not set
# CONFIG_NOHIGHMEM is not set
# CONFIG_HIGHMEM4G is not set
# CONFIG_NUMA is not set
# CONFIG_DISCONTIGMEM_MANUAL is not set
# CONFIG_SPARSEMEM_MANUAL is not set
# CONFIG_SPARSEMEM_STATIC is not set
Thanks in advanced.
