Disk usage is not within je.maxDisk or je.freeDisk limits and write operations are prohibited

I'm seeing errors related to disk usage and configuration, namely "Disk usage is not within je.maxDisk or je.freeDisk limits and write operations are prohibited".

Complete log entry:

SEVERE Failed to start bean 'bdb'; nested exception is java.lang.RuntimeException: com.sleepycat.je.DiskLimitException: (JE 7.5.11) Disk usage is not within je.maxDisk or je.freeDisk limits and write operations are prohibited: maxDiskLimit=0 freeDiskLimit=5,368,709,120 adjustedMaxDiskLimit=0 maxDiskOverage=0 freeDiskShortage=10,711,040 diskFreeSpace=5,357,998,080 availableLogSize=-10,711,040 totalLogSize=1,266 activeLogSize=1,266 reservedLogSize=0 protectedLogSize=0 protectedLogSizeMap={}

Where is je.maxDisk adjusted?
