FMP Server Advanced Instant Web Publishing IWP Service Unavailable error
I upgraded from FMP Advanced v11 to v12 this summer. Never had a problem last year.
I did a completely clean install of the Mac OS X and FileMaker, so there was no "cruft" on the server.
Also, the server is beefier this year, with more RAM and a faster processor.
My users are frequently getting this error:
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
A restart of the server fixes the situation, but I shouldn't have to do this.
