[CentOS] Intermittent problem, likely disk IO related - mptscsih: ioc0: attempting task abort!

NOTE: this is happening on Centos 6 x86_64, 2.6.32-504.3.3.el6.x86_64 not Centos
5

Dell PowerEdge 2970, Seagate SATA drive, non-raid.

I have this server which has been dying randomly, with no logs.

I had a tail -f over ssh for a week, when this just happened.

Feb  8 00:10:21 thirteen-230 kernel: mptscsih: ioc0: attempting task abort!
(sc=ffff880057a0a080)
Feb  8 00:10:21 thirteen-230 kernel: sd 4:0:0:0: [sda] CDB: Write(10): 2a 00 1a
17 a1 6f 00 00 01 00
Feb  8 00:10:51 thirteen-230 kernel: mptscsih: ioc0: WARNING - Issuing Reset
from mptscsih_IssueTaskMgmt!! doorbell=0x24000000
Feb  8 00:10:51 thirteen-230 kernel: mptbase: ioc0: Initiating recovery
Feb  8 00:11:13 thirteen-230 kernel: mptscsih: ioc0: task abort: SUCCESS
(rv=2002) (sc=ffff880057a0a080)
Write failed: Connection reset by peer

After reading https://access.redhat.com/solutions/108273, I am increasing the
logging (shown below) but I am not confident about this wait and see approach.

sysctl -w dev.scsi.logging_level=98367

I am also going to check smartctl output once I get onsite to power cycle the
system.

Other posts I have read, but I can not act on yet:
