So I'm relatively new to this forum, but I can't find an explanation of a problem I'm receiving anywhere, so I thought I'd ask the question in here. Currently, our system is running FM server 5 and hosting a number of files (~70). The client-side computers are running Filemaker v5.5, one running v6.

I have just recently taken over managing this database, and can't honestly say what I've done to cause the problem, as I've only been adding buttons that implement various types of finds on records, but the error I get is:

Communication with the host was interrupted and could not be re-established (-20).

Before I try to restore backups(which would cause some data loss that I'm not prepared to accept), I would like to know what this error is, and if anybody else has seen it, and what they did to alleviate it.

Probably not the answere you are looking for, but I have been and continue to be the victim of the very same said error -20. As far as I can tell, it happens when the client loses the connection to the host. We do not use fm server (less than 10 machines on the network and only about 5 of those are db users), so I just have one machine sitting there acting as the host with all the files on it and on occasion and for apparently no reason that error -20 pops up and the client files closes down. I know for certain that this will happen if the host closes the file, but it also happens even when the host file is still open. When this happens I usually just go back to "Open Remote" and re-open the file.

I am sure someone else may have an actual solution for you, but atleast you know you are not alone and that it probably does not have anything to do with your actual files.

Well, assurance that I'm not alone does improve my mood a bit. What bothered me most about this error is my never seeing it before, and when I took over responsibility of the files and the server, it started happening.

Why, oh why, Murphy, must your laws abide to me?
