Hi Clint, Would you please send me the output of the following command, executed by the LDM user: grep -i '^request' /home/ldm/etc/pqact.conf Are you logging metrics as outlined at <http://www.unidata.ucar.edu/software/ldm/ldm-current/basics/monitoring.html#metrics>? If so, would you please send me screenshots from the following command, executed by the LDM user: ldmadmin plotmetrics -b 20151001 Alternatively, add the entries in the attached file to the LDM user's "~/.ssh/authorized_keys" file and I'll look at your setup myself: > Hi Steve (probably), > > I just installed LDM (6.12.14) on a new server and am getting a message that > I have never seen before. > vetQueueSize(): The maximum acceptable latency (registry parameter > "/server/max-latency": 3600 seconds) is greater than the observed minimum > virtual residence time of data-products in the queue (247 seconds). > This will hinder detection of duplicate data-products. > vetQueueSize(): The queue should be 83308854029 bytes in size with > 2301904 slots or the maximum-latency parameter should be decreased to > 247 seconds.
