The source shows:

It's an enomem().

It's triggered if maildirwatch_alloc(minfo.homedir) returns null.  **

Unfortunately, looking at the source of maildirwatch (in
maildir/maildirwatch.c), it can return null in quite a few different
conditions:
- cannot get current working directory
- memory allocation failures
- if you have FAM, a failure in FAMOpen

Currently Sam is making a decision as to how to handle stderr output from
the sqwebmail daemon; maybe soon you'll be able to put fprintf(stderr,...)
lines in there and have them captured to syslog.

In the mean time, you can either open a debug file and write to it, or you
can call syslog() explicitly, if you want to find out exactly what is going
on.

** in turn, minfo.homedir comes from maildir_info_imap_find(&minfo,...) which
I guess uses the shared index file. So perhaps you have not populated that
file correctly. Care to show an example of what you have put in it?

However I can't really understand what is going on in the source here, since
it's a "homedir" value from maildir_info_imap_find() which is being passed
to a "maildir" argument of maildirwatch(). I'd have to start putting
printf's in just to work out what is supposed to be happening.

If all that is correct, then it just might be a problem with FAM. However
there doesn't seem to be a ./configure --without-fam option. You might want
to try temporarily renaming fam.h and libfam.{a,so*} so that they can't be
found, recompiling courier, and then putting them back.
