ENTERPRISE REPLICATION

Hi Informixs, I need some help in enterprise replication. I had worked with it since HDR, but now I have got some problems. I have a Primary_target replication scheme using a central server and four remote destinations with a 64kbps satelital connection. Sometimes replication just don't work, some rows doesn't get replicated and I don't know why? I have checked logical logs in all installations and all are working properly, by the way all destination use continous logical logging (ontape -c). Another key, there is not information in message queue files of ATS,RTS...... Could u tell me if I am doing something wrong? and why it happens now and not before? Hardware Features: 1 SUN Ultra 4000 Sparc Server 4 Sparc 5 destinations. Software Features: Informix DSA 7.22 in all servers. Sun Solaris 2.5 Operating System Thanks in advance for any suggestions or idea Javier Puente Corporacion Noboa
