How do I import multiple dumps into one schema in the same import?

The imp command I used is as follows:

imp system/**** file=ml0.dmp,ml1.dmp,ml2.dmp,ml3.dmp,ml4.dmp parfile=imp_maskop.par log=imp_maskop.log

Here is the parameter file:

fromuser=AM
touser=MASKOP
ignore=Y
rows=Y
tables=(ACTIVITY_LOG, ACTIVITY_RESULT, FILE_REC, JOB, LETTER)
filesize=629145600

(filesize was specified in the export. So I am using that here as well, without which I was getting another error)


Here is what I see when I run the import:

Export file created by EXPORT:V08.01.06 via conventional path
Warning: the objects were exported by AM, not by you

import done in UTF8 character set and AL16UTF16 NCHAR character set export client uses US7ASCII character set (possible charset conversion) export server uses WE8ISO8859P1 NCHAR character set (possible ncharset conversion)

. importing AM's objects into MASKOP
. . importing table "ACTIVITY_LOG"./imp_softshoe.sh: 21061756 Memory fault(coredump)


The import starts and errors with a core dump.

The export log says the following:

Connected to: Oracle8i Enterprise Edition Release 8.1.6.2.0 - Production

So, why the core dump error? What am I doing wrong in running the import if anything? Thanks.
