Hi Evan, re: > I am running an LDM at a remote location.

It was > plugged back in and I stopped the LDM. When I tried to restart the LDM I got a > message saying there was a pq error and to execute ldmadmin clean. I did that > and tried to restart again. Then I got a message to use pqcat and pqcheck. I > did that and restarted the LDM. I executed ldmadmin watch and no products were > showing up. This typically happens when the LDM product queue, ~ldm/data/ldm.pq, is damaged. > I executed ldmadmin stop and the message "Waiting for LDM to > terminate" repeats. I let this persist for nearly 30 minutes and still > nothing. This indicates that a process was hung and needed to be killed by hand. It is my experience that one typically needs to send a 'kill -9 <pid>' signal to the hung process to kill it, and sometimes even that will not work. I the latter case, one is forced to reboot the machine to clear the hung process. > When I execute ldmadmin clean it says another LDM server is running > and to stop it first. ldmadmin watch does not respond to a CTRL+D command > (only CTRL+C). The log says the LDM operation has been terminated. > > Please advise, If you are unsuccessful in killing the hung process, I would reboot. If you can kill the hung process, I would then do the following: ldmadmin clean ldmadmin delqueue ldmadmin mkqueue ldmadmin start If you are forced to reboot, you may still be required to run this sequence to get things running again. > thank you, No worries.
