ActiveMq and solaris

[Datacom - Marcelo]

Hi, we are facing a problem with solaris 8, we use activemq in a windows 
xp box as a server. All clients (other windows stations) can connect 
into this server, including the clients located in the server. When we 
installed a client in Solaris, this client does not receive any messages 
from server (the other clients still receive messages). We removed the 
server (activemq) from windows and installed in solaris and every 
station now receives all messages (windows and, we just have one 
solaris, the localhost solaris). All acess via JDBC, sockets work fine, 
only jms messages are missed by solaris when client. Is there a possible 
problem in solaris configuration  ?

Thanks in advance,
