Archive seems to be failing

The DB is IDS 7.31.UC6. I was looking at the online.log this morning and discovered these lines: 22:10:10 Level 0 Archive started on rootdbs, hutrep_dbs, gendbs, eom_dbs 23:00:52 Checkpoint Completed: duration was 14 seconds. 23:51:01 Checkpoint Completed: duration was 9 seconds. Fri Dec 23 00:20:04 2005 00:20:04 Archive on rootdbs, hutrep_dbs, gendbs, eom_dbs ABORTED. 00:20:04 Aborted by client. 00:25:21 Checkpoint Completed: duration was 8 seconds. Going back i discovered that the last archive that completed was Nov 27, but there were regular failures before that. Also, almost every failure (9/10) is exactly at 00:20:04 (if not at this time then it was random) The homegrown script that runs the backup has been telling me that everything was OK, so I haven't been worried. However another log that I've just discovered has this line in it: Archive failed - buc_fe.c : Archive API processing failed at line 291 for msgtype This log only maintains the information for the last backup so I can't investigate a pattern. However, I'm now pretty sure that the backups haven't worked for a month. I've done some Google research but nothing that I found gave me an idea as to how to fix it (except DBSPACETEMP which is pointing to 3 different large temp DBSPACES). Can anyone help? Thanks in advance and a Merry Xmas and a SAFE and HAPPY NEW YEAR to all!
