Hi Alex, It seems strange to me that only this station is filling it's import table. At the rate it's filling now i guess it'll be at 0 early next week. What happens when the table is full? Smurfed fields? I can reboot on monday. I'll have a look at the BO400BZ.

Total number of entries used to save station addresses for I/A objects to minimize Message multicasts. ? You can use the /usr/local/show_params utility to view the usage of I/A objects imported. ? You can use the /opt/fox/bin/tools/som utility (?imp? command) to view the names of imported I/A objects (for example, compounds). The filling of the table is a good thing; that means you are minimizing the multicasts from the system. If you can reboot the machine, you can increase the OM_NUM_IMPORT_VARS by following the instructions in Application Object Services User?s Guide (B0400BZ) for information on setting OS configurable parameters.

(last rebooted on june 23.) I could reboot to reset, but I would like to find out what's causing it. Any rsom/som tips? ( i couldn't find any info on rsom/som in BO193BC, maybe I've been looking in the wrong place?)
