Hi,

The following line:
error_logger:info_msg("[~p]:~ts~n", [PPid, Doc])

prints (Doc is data from the wire - untouched):

it logs to the file log: /var/xpp/logs/error_log
and also to the stdout and then generates the error:
'gen_event handler error_logger_file_h crashed'

and logging is not performed anymore in file log,
only to stdout.

the app is running in shell mode

The full (lengthy) error follows (sorry for the length of error):

------END-OF-ERROR--------

it seems error_logger is unable to
interpret romanian diacritics.

without t modifier from "[~p]:~ts~n"
the crash does not happens.

What can be done to at least make
error_logger log to the file log again
after this crash occurs?
