Hi,
one of our customer has an Ironport cisco appliance C160.
The following message has been sent out by the IronPort since yesterday :
The Critical message is:
An application fault occurred: ('journal/chunk.py unpack_header|113', "<class 'journal.exceptions.CorruptError'>", "CorruptError: Invalid chunk type: 'L'", '[event_router/event_router.py _journal_reader2|267] [journal/reader.py dequeue|76] [journal/base.py _with_mutex|1062] [journal/reader.py _dequeue|103] [journal/base.py _read_chunk|275] [journal/base.py _do_read_chunk|315] [journal/chunk.py unpack_header|113]')
Last message occurred 240 times between Wed Apr 5 06:56:51 2017 and Wed Apr 5 07:56:43 2017.
may be the error is well known and you have workaround for it.
Many thanks
Dmitry from NTT Team
