In a NW04s install, my defaultTrace file repeats the error:
#1.5#0003BADBD6440001000000D100001D9B00041E4CAA35948D#1159214528828#com.sap.engine.core.locking.impl3.LockingManagerImpl##com.sap.engine.core.locking.impl3.LockingManagerImpl.jenqulib#######Thread[SAPEngine_EnquReader,5,main]##0#0#Error#1#/System/Server#Plain###Encomi: failed to connect to nyerpnp1/3289/Connection refused)#
Port 3289 is the enqueue port. The message server port is 3569. The logs in the SCS89/work directory don't show any errors starting the enqueue or MS host. The port is definitely correct according to the configtool.
I'm not sure where else to look at the root cause - any ideas?
This is a J2EE ONLY install. No ABAP.
