*Network error* message received from onmonitor in Informix ODS v7.23 on Solaris

Any help I could get with the problem I've described below, trying to run multiple instances of Informix ODS v7.23 on Solaris 2.5.1, would be greatly appreciated! I'm getting a "*network error*"" message on the console from a second Informix instance while inside the onmonitor utility. Both instances are online, but we only connect to the first. Any ideas why? Our second instance's sqlhosts file looks like this... m7dev ontlitcp m7dbserver turbodev and here are a few selected entries from the second instance's onconfig_m7dev file... SERVERNUM 1 DBSERVERNAME m7dev NETTYPE tlitcp,1,20,NET Note that the turbodev service has been added to the /etc/services file as port 1529, chosen arbitrarily, but ensures no conflict with the first instance running on port 1528. This error message doesn't occur on the primary instance of Informix we first installed on port turbo/1528, which we called m7server. As you can see below, we established an alias with the first instance but not with the second instance described above. Here's the info on this primary instance: Primary instance's sqlhosts file... m7server ontlitcp m7dbserver turbo m7pipe onipcshm m7dbserver notused and selected entries from onconfig_m7 file... SERVERNUM 0 DBSERVERNAME m7pipe DBSERVERALIASES m7server NETTYPE ontlitcp,1,200,NET NETTYPE onipcshm,1,10,CPU
