Something corrupted /var/lib/univention-directory-listener/cache.db
UDL detected that and created /var/lib/univention-directory-listener/bad_cache
The error message could not be found in /var/log/univention/listener.*
Since then UDL *silently* refuses to start; only DEBUG_INIT is logged!

$ git grep -n bad_cache
src/cache_lowlevel.c:274:                       if (asprintf(&f, "%s/bad_cache", cache_dir) < 0) abort();
src/main.c:520: if (asprintf(&f, "%s/bad_cache", cache_dir) < 0) abort();

1. We should print an very visible message in both cases before abort()ing UDL!

2. The file itself should contain the error message, which currently is logged
  univention_debug(UV_DEBUG_LISTENER, UV_DEBUG_ERROR,

3. The Nagios check should check for that file and yell if it is found.

4. Same for the diagnostics module.
