Hi there,
here's a neophyte with massive problems.
After unsuccessfully posting in port-i386 I thought posting here
might get me a little help... <:^)
Here goes:
I keep having kernel crashes and always need to reboot the machine.
Mostly the crashes occur during mysql queries on large tables.
The mysql logs do have some IP connection errors, but the Hardware
and TCP/IP configuration seem ok.
Here's the output on the screen:
uvm_fault (0xe384d814, 0x0, 0, 1) -> 1
kernel: page fault trap, code=0
Stopped in mysql at pmap_page_remove+0xb7 movL 9x4(%ebx),%edx
The kernel is still generic, so I tried to compile a new Kernel with
IPv6 disabled (i thought this might be a reason for my problems).
When I first started make, the compiler stopped with the following:
internal compiler error:program got fatal signal 11
***Error code 1
I erased the custom kernel directory under /compile, config'ed anew
( didn't forget make depend, no)and started make again, the kernel crashed
with the following:
uvm_fault (0xe384d814, 0x0, 0, 1) -> 1
kernel: page fault trap, code=0
Stopped in mysql at pmap_page_remove+0xb7 movL 9x4(%ebx),%edx
Notice something? Same address!!!
Here's some additional info:
Version is NetBSD 1.5.2
Mysql 3.23.25 (the one from the packages)
My boss will to rip me into pieces if I don't get down to that soon...
:^/
What could be the problem here and more important - the solution..?
Any Ideas?
Help is very much appreciated...
<:^)
