It's connected to 4TB of SAN space using dual HBAs. Today, I had two instaces of page allocation failures (see info below). The box has been up for some time with no issues (never seen this before). Is there any tuning I can do to fix this? I've changed min_free_pages to 32MB (from defauly of ~3MB) and I read somewhere that giving kswapd a littl= e higher priority can help (I reniced it to -5) though there's a lot of stuff on the Internet that's wrong ;).

CPU P4 box w/ HT enabled and 2GB RAM that is a heavy load NFS se= rver in a HPC environment (it's an IBM x345 system).  It's connected t= o 4TB of SAN space using dual HBAs.  Today, I had two instaces of page= allocation failures (see info below).  The box has been up for some t= ime with no issues (never seen this before).

Is there any tuning I can do to fix this?  I've changed min_fr= ee_pages to 32MB (from defauly of ~3MB) and I read somewhere that giving ks= wapd a little higher priority can help (I reniced it to -5) though there's = a lot of stuff on the Internet that's wrong ;).
