From your description, the dump tran frequency is high ( every 10 minutes through cronjob ),
I will suggest you to enlarge your log space to at least 3 times of current log space.
normally, 10~25% of data space should be consider to allocate for log space in the beginning,
and you really need to estimate appropriate log space for your production ASE by monitoring your daily activities (task type - OLTP, OLAP, batch ).
And you might need to consider to put your long running tasks to non-peak time to avoid impact to you OLTP tasks since you are not able to dump tran to release active part of log space.
HTH, Thanks.
