For what it's worth I'm experiencing the same problem on a vastly
different setup. My setup is as follows:
hda Maxtor 90845D4 (8.4GB)
Device Boot Start End Blocks Id System
/dev/hda1 1 255 2048256 fd Unknown
/dev/hda2 256 1024 6176992+ 5 Extended
/dev/hda5 256 510 2048256 6 FAT16
/dev/hda6 511 638 1028128+ 83 Linux
/dev/hda7 639 893 2048256 83 Linux
/dev/hda8 894 1010 939771 83 Linux
/dev/hda9 1011 1024 112423+ 82 Linux swap
hdc QUANTUM FIREBALL ST4.3A (4.3GB)
Device Boot Start End Blocks Id System
/dev/hdc1 1 255 2048256 fd Unknown
/dev/hdc2 256 383 1028160 83 Linux
/dev/hdc3 384 524 1132582+ 5 Extended
/dev/hdc5 384 397 112423+ 82 Linux swap
/dev/hdc6 398 524 1020096 83 Linux
contents of /etc/raidtab
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
persistent-superblock 1
chunk-size 4
device /dev/hda1
raid-disk 0
device /dev/hdc1
raid-disk 1
contents of /proc/mdstat (linear is not currently used in system)
Personalities : [linear] [raid1]
read_ahead 1024 sectors
md0 : active raid1 hdc1[1] hda1[0] 2048192 blocks [2/2] [UU]
unused devices: <none>
The symptoms are IDENTICAL to what has been described with the exception
that I can usually get uptimes of about 24-36 hours without any
problems, fortunately this a home system so it's not severe having to
reboot once a day.
It seems as though the current processes keep running, but it is unable
to spawn any new processes. This would explain why the first connect
will work and further ones don't. This also explains the problem with
logins from the console as the login program needs to spawn other
programs.
In general it seems as though the system is performing as though it was
out of processes. However the keyboard is responsive for switching
terminals, indicating that it isn't overloaded.
At first I thought this was a hardware problem, as a flaw with my
motherboards IDE controller causes it to not write all the data once in
a while. However, now that I see someone else is having a similar
problem I figured I would speak up.
Also, I'm not entirely sure on this, as it might be from my faulty IDE
controller but I've seen messages on the screen complaining of lost
interrupts on hda and hdc.
I'm currently running kernel 2.2.14 with the raid-2.2.14-B1 installed.
The kernel also has the ppscsi patch installed and some additional
patches for the matrox framebuffer device, but the problem persists if
those modules are loaded or not.
I'd appreciate any help from the list. I realize some of my problem is
the bad IDE controller, but it's been locking a lot more since I RAIDED
my boot device (on the plus side, I'm no longer loosing data).
