GoldenGate Replicat Process Abending due to Tablespace Full and Discard File Exceeding Max Bytes

We have a cron job set up to monitor errors in the GoldenGate ggserr.log. This monrining, in a target database, we recieved:

< 2013-06-17 02:58:17  ERROR   OGG-01172  Oracle GoldenGate Delivery for Oracle, rvasip.prm:  Discard file (./dirrpt/RVASIP.dsc) exceeded max bytes (1000000).
< 2013-06-17 02:58:17  ERROR   OGG-01668  Oracle GoldenGate Delivery for Oracle, rvasip.prm:  PROCESS ABENDING.

It appeared that Replicat process abended due to  Discard file exceeded max bytes.
Discard file is used by GoldenGate to log records it cannot proccess. The maximum size of the discard file can be specified by MAXBYTES or MEGABYSTS options,
the defaults are 1000000 or 1MB.  If the specified size is exceeded, the process will abend.

Further troubleshooting showed the reason for the discard file filled up was due to a tablespace filled up in this case. In the RVASIP.dsc files we can found:

OCI Error ORA-01653: unable to extend table PPOWNER.VZ_JNR_FEED_TRX_LOG by 8192 in tablespace PPOWNER_DATA_1 (status = 1653). INSERT INTO "PPOWNER"."VZ_JNR_FEED_TRX_LOG" ("ID","JOURNAL_ID"
,"TRX_EXT_ID","BILLED","DB_MODIFICATION_DATE","DB_CREATION_DATE","SUB_TRX_ID","TRX_ID","CHG_ATTR","ACCESS_TYPE") VALUES (:a0,:a1,:a2,:a3,:a4,:a5,:a6,:a7,:a8,:a9)
Aborting transaction on ./dirdat/rt beginning at seqno 21275 rba 3795007
                         error at seqno 21275 rba 5169654

To fix the problem, I renamed RAVSIP.dsc, changed the max bytes of discard file to be 10MB in the parameter file:

discardfile ./dirrpt/RVASIP.dsc, Append,megabytes 10

Then I stopped and started the Replicat process. I have verified that those discarded dmls recorded in the discard file have been applied after Replicat process re-started. no manual intervene is ndeed.
