Hi Chi,

re: CONDUIT reception errors on March 8

Very true, but we saw two types of errors yesterday:

Name server problem:

Mar 8 10:03:03 daffy ncepldm1.woc.noaa.gov[6412] ERROR: Couldn't get IP address 
for upstream host ncepldm1.woc.noaa.gov; Couldn't resolve 
"ncepldm1.woc.noaa.gov" to an Internet address in 25.053 seconds; hostname 
lookup timeout

Connection reset by peer:

Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6412] ERROR: readtcp(): read() error 
on socket 4
Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6412] ERROR: one_svc_run(): RPC 
layer closed connection
Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6412] ERROR: Disconnecting due to 
LDM failure; Connection to upstream LDM closed
Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6412] NOTE: LDM-6 desired 
product-class: 20110308162024.578 TS_ENDT {{CONDUIT, "[18]$"},{NONE, 
"SIG=36e2c8b2b3c72b005a5774c9212d3537"}}
Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6410] ERROR: Connection reset by peer
Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6410] ERROR: readtcp(): read() error

Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6410] ERROR: one_svc_run(): RPC

Mar 8 10:20:24 daffy ncepldm1.woc.noaa.gov[6410] ERROR: Disconnecting due to 
LDM failure; Connection to upstream LDM closed

The connection reset by peer errors would not be mitigated by the downstreams
(us, UW/AOS, PSU, UIUC) requesting by IP.

Cheers,

Tom
