we use bdb je in replicated environments with 10 billion records per day ,and met some problem about reclaim log files and delete reserved log files.

As descipted in Getting Started with High Availability Applications :

"For replicated environments, JE hangs on to log files as long as possible in case they are needed to bring a replica up to date. Log files that have been cleaned but then saved due because of replication are in a reserved state. All such files are retained until the disk usage thresholds as defined by EnvironmentConfig.MAX_DISK and EnvironmentConfig.FREE_DISK are exceeded. At that point, JE deletes reserved log files."

In out project , write operations are increasing quickly sometimes. And if the disk usage thresholds are approaching , the replicated environment throws DiskLimitException and write operations are prohibited because of the speed of delete file cannot match the speed of write data . So I'm really want to know if there is a way to delete reserved files manually instead of dependent on the the disk usage thresholds .

we use je.properties to config out HA environment and content is like :

 je.log.fileMax=1073741824
 je.lock.timeout=3000000
 je.sharedCache=true
 je.maxMemoryPercent=50
 je.rep.txnRollbackLimit=1000
 je.rep.replicaReceiveBufferSize=4194304
 je.rep.feederBatchNs=10000000
 je.rep.feederBatchBuffKb=256
 je.rep.commitToNetwork=false
 je.rep.replicaMessageQueueSize=10000
 je.rep.insufficientReplicasTimeout=5000 ms
 je.rep.replicaAckTimeout=10000 ms
 je.cleaner.minUtilization=50
 je.rep.replayFreeDiskPercent=50
 je.env.runCleaner=false
 je.rep.designatedPrimary=false
 je.env.backgroundReadLimit=20
 je.cleaner.readSize=33554432
 je.cleaner.detailMaxMemoryPercentage=5
 je.cleaner.lookAheadCacheSize=32768

In our project , we use ReplicatedEnvironment.cleanLogFile() telling je to clean file , and use ReplicatedEnvironment.removeDatabase(null, "persist#" + storeName + "#com.sleepycat.persist.formats") to declare one EntityStore can be cleaned.

Any advise will be appreciated.
