I'm not sure if you edited your log for confidentiality or something, but this looks wrong:
(Fri May 02 11:28:23 PDT 2014) II:NOTICE [NioComNetworkParent v24745] {ComModuleSpop:20} Making install request to: IPADDRESSManagerInstallPort=37890;
(Fri May 02 11:28:23 PDT 2014) WW:WARNING [NioComNetworkParent v24745] {ComModuleSpop:20} Failed to bind socket to local port in range: 37893 - 37896 or to connect to manager at IP ADDRESSManagerInstallPort=37890/37890 for message 0;
On my nodes, those lines look like this:
(Mon May 05 07:30:56 MDT 2014) II:NOTICE [NioComNetworkParent v24745] {ComModuleSpop:21} Making install request to: 10.110.7.4;
So your IP address appears to have "ManagerInstallPort=37890" appended to it, which makes it invalid as an IP or hostname, which could be the issue. If you didn't sanitize your logs, it appears that your Agent picked up IPADDRESS as a hostname, which might also be part of the problem.
On your server:
cd /usr/local/contego
cat spop.conf
Is there a carriage return at the end of the ManagerAddress= line? Is the value for ManagerAddress correct?
