It can be a problem because you're writing so many messages into the System Log, and eventually every server hits it's limit.
Depending on the regulations you need to comply with, you may actually need to keep all these messages. If that's the case, then you need to make the database faster, possibly by moving up to SSDs for the database and transaction log filesystems.
Normally, I recommend you keep all logging turned on, but just keep that data for a shorter period of time.
If you want to keep all the log data, you can use the logging exit, and use some custom code to write the log data you need to keep (but don't necessarily want in the system log). The snag here is that there are limitations to the number of times you can write to a file per second as well.
