If I use this command: TELL LISTSERV SHOW NODE GITVM1 on my own LISTSERV, it works fine. If I use this command: TELL LISTSERV AT UABDPO SHOW NODE GITVM1 from another system, LISTSERV gets a REXX error. If I send this command to some LISTSERVs in my region, they also get REXX errors. The problem appears to be in the logic that sends responses back via mail instead of messages. I think this problem only started after I applied 17a-003o and 17a-005o a few days ago. The other LISTSERVs mentioned above also have 17a-003o. Is this a known problem? Eric, do you need more information about the problem? Console messages or anything like that? Since I think LISTSERV sends a message back to Eric every time this error occurs, I would ask for now that everybody not rush out to try to recreate the error if you haven't encountered it. I probably filled up Eric's mailbox yesterday just trying to pin down the problem here. As always, messages pointing out any error in my ways will be humbly accepted. Thanks.
