Hi Jérémie,
The next panic - again exactly at the same place. Your patch below produced the
following output:
panic: tcp_input:647: 0xfffffe84f10ac658 != 0xfffffe8522ecb1b0 - see screenshot
appended.
Again the console was frozen - I had to reset the box.
Memory wise there are two things, which I used:
For the database:
kern.shminfo.shmall=32768
Furthermore, I use a RAM disk (mfs) for tmp space: In /etc/fstab:
swap /rd mfs rw,-s=1000000 0 0
However, This all worked for years under 5.2 and older releases.
It seems, the system is running for about 3 - 5 days, and then the kernel
crashes.
Is there a way to patch the kernel at tcp_input to automatically generate a
core, if it crases?
Any further suggestions?
- Peter
