Hello,
This error Ora-4031 indicates a memory pressure on the area Shared Pool of the SGA.
I imagine that this capture process is integrated type. And use the streams Pool for the generation of the LCR.
Check out the file alert_SID.log to get  more information.
Have you used the max_sga_size parameter in the capture process?
If not used 1GB of memory used in Streams_Pool SGA by default.
How much memory defined in Streams_Pool?
Use the automatic memory model AMM? Check the SGA configuration parameters , like memory_target,max_memory_target, sga_target, max_ sga_target.
I think there might be some complex transaction that requires a lot of memory using the Streams Pool.
You can use the Streams memory Advisor to see the memory allocation stats.
Run this query
select * from V$STREAMS_POOL_ADVICE;
