Oracle Database Discussions

Since a week ago I had noticed in my alert log the following message repeated many many times:

Transaction recovery: caught and ignored

I suspect this is related with a big datapump import operation that I did and do not end due to I cancelled it because of errors. After that the frecuency of the log switch began to occur too fast(every 20 seconds, redo size 50MB).

Actually I have not idea about what can be happening so I aprecciate any help you can give me.

Thanks very much.
