[syslog-ng] UDP Works, TCP Does Not

All, I am new to syslog-ng and want to use it for tcp remote logging, (without ssh at this time). I am testing from a Solaris 10 box, sending logging files to another Solaris 10 box. It sends them via udp just fine. But when I change that to TCP, no logging. Not finding much on the internet around this subject. If anybody has any info regarding this, please send my way. Thanks, Scott
