Slava> What's your Linux kernel version, and what distribution are you running?
I'm running under Debian stable (5.0), kernel 2.6.26-2-686. The errors
occur with today's binary release, factor-linux-x86-32-2009-10-20-06-56.
I built clean-linux-x86-32 from git yesterday, and having run
'"io.monitors" test' on that just now, it doesn't produce errors in the
listener but it does dump the following to stderr:
Error in thread 276 (Recursive monitor pump, [ ~recursive-monitor~
pump-thread ]):
Unix system call âlstatâ failed:
No such file or directory (2)
It was called with the following arguments:
"/home/conrad/factor/factor-clean-linux-x86-32/temp/doesnotexist"
S{ stat f 0 0 0 0 0 0 0 0 ~ushort-array~ 0 0 0 ~timespec~...

I'm reasonably experienced with C & some Linux kernel hacking, so could
poke at the C inotify API on my machine to see if I can turn up anything
useful there. I note that errno 28 (ENOSPC) is a documented failure
mode for inotify_add_watch --- from the man page:
ENOSPC The user limit on the total number of inotify watches was
reached or the kernel failed to allocate a needed resource.
A trivial piece of code calling inotify_init, inotify_add_watch and
inotify_rm_watch directly from C doesn't turn up any errors for me
though; the inotify system limits on my machine are as follows:
max_queued_events 16384
max_user_instances 128
max_user_watches 8192
