[hunchentoot-devel] less-than-helpful error message - tbnl-devel@common-lisp.net - mailman3.common-lisp.net

      Esteemed hunchentoot developers,
So, while trying to track down an unrelated issue where my handlers aren't getting called anymore, I came across the following issue where failure to open the message log file results in an error, which, in turn, attempts to open the message log file. The problem in this case was that the permissions were bogus for the directory I was trying to open. But, still, we should probably have a nicer error message than "recursive lock attempt" here.
thanks,
Cyrus
