Michael, It's too bad that you can't log into the upstream system as the LDM user. That would help a lot. Here are the log messages from the downstream LDM process on your system that requested MRMS data: Mar 30 13:06:28 crh-ls-ldm-vm 140.90.98.15[12730] NOTE: Starting Up(6.10.1): 140.90.98.15:388 20150330120628.338 TS_ENDT {{EXP, "(MRMS|xmrg)"}} Mar 30 13:06:28 crh-ls-ldm-vm 140.90.98.15[12730] NOTE: Previous product-information file ".04678c053d959bab4a5dfcc7d651ed3e.info" doesn't exist Mar 30 13:06:28 crh-ls-ldm-vm 140.90.98.15[12730] NOTE: LDM-6 desired product-class: 20150330120628.340 TS_ENDT {{EXP, "(MRMS|xmrg)"},{NONE, "SIG=b1cd343f31293b0653440ea4d6780e3f"}} Mar 30 13:06:28 crh-ls-ldm-vm 140.90.98.15[12730] NOTE: Upstream LDM-6 on 140.90.98.15 is willing to be a primary feeder Mar 30 14:46:00 crh-ls-ldm-vm 140.90.98.15[12730] ERROR: readtcp(): select() timeout on socket 4 Mar 30 14:46:00 crh-ls-ldm-vm 140.90.98.15[12730] ERROR: one_svc_run(): RPC layer closed connection Mar 30 14:46:00 crh-ls-ldm-vm 140.90.98.15[12730] ERROR: Disconnecting due to LDM failure; Connection to upstream LDM closed Mar 30 14:46:00 crh-ls-ldm-vm 140.90.98.15[12730] NOTE: LDM-6 desired product-class: 20150330134600.907 TS_ENDT {{EXP, "(MRMS|xmrg)"},{NONE, "SIG=2168fa14d86960e9e18d0d2e8c093f99"}} Mar 30 14:46:01 crh-ls-ldm-vm 140.90.98.15[12730] NOTE: Upstream LDM-6 on 140.90.98.15 is willing to be a primary feeder They show that it started at 13:06:28 and requested the last hours worth of data. About 1 hour and 40 minutes later (at 14:46:00) the connection to the upstream LDM broke and was re-established within a second. All this behavior looks perfectly normal. Did MRMS data-products continue to arrive after 14:46:01? > Hi Steve, > Unfortunately I don't have access to the upstream system short of > connecting via ldm for data transfer.
