Answer / michael ojejinmi

to resolve this what i did was to stop and restart the
capture and apply processes on the source and destination
databases, and this resolved the problem.

Answer / michael ojejinmi

Also if you don't dedicate a large enough streams pool size
to your source database, then the streams process uses your
shared pool(about 10% of it), if thats already pegged by
not using binds, then there'll not be enough shared memory
for your source database queue, thereby resulting in a
queue buffer overflow, so increase your streams_pool_size
parameter, that should help with the ORA_25307 error.
