Yesterday Aleph stopped when our ora01 volume ran out of space.
The /ora01/oradata/aleph1/arch directory contained 182 GB worth of archivelog files, so I deleted a bunch of those from the earliest through 1/23. However, he earliest weren't older than 1/19.
Looking at the most recent logs for hot, cold, and archivelog backups, I didn't see anything that would indicate that Oracle was keeping more archivelog files on the /ora01 volume than it normally would, so unless the oracle data files themselves have suddenly grown a lot bigger, I'm thinking that it must be that there were a lot more archivelog files than usual (they're all 48MB, but there are lots of them).
An examination of the /ora01/oradata/aleph1/arch showed that arch_aleph1_... files were being created at a rate of 4 gig/hr.
The "top" command showed this:

"ps -ef" grep for this rts32 process# 25435 showed this:

ue_11 runs in the $usr_library. To see the $usr_library, do this:
Looking at the abc00 $data_scratch we see this:

These logs have entries like this:
2009-01-26 08:45:12 Update : c 00 CEN02 ABC01:
2009-01-26 08:45:12 Error: io_z105 - table doesn't exist in database or tab_io_remote for library: 'CEN02'.
The ABC01 tab_z105 has this line referencing CEN02:
NEW-DOC c CEN02
SKB 8192-5046 addresses this.
SKB 8192-4344 explains that ue_11 continues to try writing the z105 when it fails (assuming that the reason is a duplicate timestamp); that's why such large logs are being written.
