There's no report for this WU in the DB yet.

I don't know what's going on with your machines, but there is definitely something wrong ... you shouldn't see so many errors ...

Posted: **Fri Apr 17, 2009 12:19 pm**

I have no idea what the current statistics are because I don't really monitor the system very often. Usually, I don't see the problem until I refresh the FAH stats page at ExtremeOverclocking, and then I would check FahMon, and then I'd check the consoles.

When you run the system headless, you don't really have a sense of what it is or isn't doing.

Ambient room temp is currently 292.7 K, so that shouldn't be the problem.

I've been able to run some various versions of Prime and they all run fine. So I don't know...

*edit*

I'm trying to remember if I had this much problems with the 2.01 core. 2.04 seemed to have more problems. 2.06 I'm seeing the WUs freeze a few times already and I would have to sent a SIGKILL(9) to it since the normal kill or pkill doesn't work.

Prime is definitively the worst stability tester for FAH ... it's not pushing the hardware hard enough.

I think your systems are mainly servers ... am I correct ? (that's why I think it's not a stability issue ... but that might be a bad memory stick ... it might happen even in professional parts ...)

Well...I have beaten it with 120 hours and 125 hours of CFD and FEA respectively and it lived through that with no errors.

And yes, it's a server.

But it also passed memtest86 even with ECC disabled.

That's definitely a strange behavior ... at least we're pretty sure it isn't hardware related.

How is your network set up ? Are you sure that you don't have some random IP resets ?

system -> 16-port netgear GS116 GbE switch -> I think it's a netgear WGR614 wireless router -> cable modem.

Host has lo and eth0. IPv6 I think is disabled entirely.

As far as I know, no. I can continuously ping somewhere, but it shouldn't matter because all of the data I/O should be going through the loopback if I understand it correctly.

I also don't know if the IP stack would report a wire being disconnected (at least to console), and I don't think that F@H has a way of reporting network or connectivity issues.

I don't know how linux handles this, but under windows, disconnecting a wire (or wireless connection), or changing the IP (DHCP renewal for instance) on a network interface also reset the loopback interface

Did you notice a regular period on the issue you're having (which might be related to an IP renewal or something similar) ? Did you try to assign static IP to your machines (in the netgear wireless router configuration) ?

Not as far as I know.

The DHCP lease period is 7 days I think. But even then, the system just picks up the same IP anyways (which I've come to accept it as being "pseudo-static" because the stupid netgear router doesn't have a way to release it from its DHCP server, even if a release command is issued).

The server never leaves the building and the only time that the IPs gets reassigned is if there's a power failure (for the whole house, since the router is on a different floor than the server).

Apparently seg faults are related to memory, memory addressing, and memory read/write issues. MY current working theory is that the F@H client isn't actually fully truly 64-bit because as I recall, only parts of it are. Therefore; with my system running SLES10 SP2 x64, and 16 GB of RAM, it might not be properly addressing all of the memory available to the system, even though the client is configured to use 16003 MB. (max available according to memstat).
