Re: DB corruption of first day of subversion

Hello,

I downloaded and ran memtest86.

I dont know whether its an error or not. But at top right hand column there
are two sections: Pass and Test.

Now, everytime I run the check, the TEST column goes from 1 to 100% and and
then it again goes back to 2% and it just stops. None of the keys work i.e.
Esc,(C)ancel and the two other keys. I need to reboot my machine.

This is the final report that is being shown after the freeze:

Pentium 4 2400 Mhz
| Pass 1%
L1 Cache 8K 19670 MB/s
| Test 2%
L2 Cache 512K 16782 MB/s
| Test [Address Test, own address, no cache]
Memory 511M 88 MB/s
| Testing 80K 511 M 511M
Chipset /* amazingly its blank but I have a geniune Intel motherboard */

Walltime Cached RsvdMem MemMap Cache ECC
Test Pass Errors ECC Errs

0:0012 511M 832K e820-std off off std 0 0 0

Is there something wrong?

Regards,
Ritesh
