So you get that written to LOG? > >Any ideas? Well something has closed (or failed to open) the POSIX-level numeric file descriptor associated with that context's STDERR. In a normal non-threaded perl that would be fd 2. But I _think_ that for complicated reasons in a threaded perl each thread - or rather each context - gets a dup()ed fd. (Complicated means I don't remember without re-reading the code ;-)) So one possibility is you just ran out of numeric fds for the number of threads/contexts you created (e.g. IIRC Solaris by deafault only has 256 fds 0..255 for compatibility reasons.)
