Server hangs every few days

[welnet]

Hello,

I have uploaded the logs here: logs. I couldn't find any errors in the logs, maybe you can take a look.

Thanks

Looking at what you have provided, the efollowing needs to be changed:
you have:
MaxBurstLength=1048576
FirstBurstLength=262144

change to:
MaxBurstLength=16776192
FirstBurstLength=65536

Also you need to make sure to change each target, not just the first one.

Overall these settings work welll:
maxRecvDataSegmentLen=262144
MaxBurstLength=16776192
Maxxmitdatasegment=262144
FirstBurstLength=65536
DataDigest=None
maxoutstandingr2t=8
InitialR2T=No
ImmediateData=Yes
headerDigest=None
Wthreads=8

And I cant see the NIC settings in your upload, but you can also try jubo frames for the NICs: http://kb.open-e.com/Does-Open-E-sup...Frames_28.html

Make sure initiators have matching settings, as this can cause the machine to seem locked/stalled.

But complete logs would give a better picture as to wether or not there are other issues.
I can only see a few files in yur link, not the whole package.

Update: i have disabled some CPU power saving features in the bios, and it is running stable now.

Unfortunately the box crashed again last night. But now i have some errors in the log:

	2011-04-12 01:59:10	scsi cmnd aborted, scsi_cmnd(0xffff88012c6d4700), cmnd[0x8a,0x 0,0x 0,0x 0,0x 0,0x 1,0xb0,0x9e,0xf8,0x 0,0x... (0/1)

This points to an hardware error. The raid controller has been replaced so it seems the backplane is not working properly.

[Gr-R]

did you ever adjust for the values I mentioned above?

[Al-S]

Please try the values that Gr-R mentioned to you, also did you checked for your RAID Controller health ?

[welnet]

The Raid controller sometimes times out accessing drives in the enclosure. It's not the same drive everytime so it must be something with the backplane.

I've changed the ISCSI values mentioned on all initiators and targets this morning. So let's see how long it keeps running this time
