Windows Policy server keeps due to out of disk space.
When investigated many mini dump files had been created in the C:\Windows\SysWOW64 directory all having the format name : hs_err_<pid>.mdmp and had filled up the C: drive.
The hs_err_<pid>.mdmp format indicated this a dump produced by a java vm.
The root cause was a problem in the JVM, causing the crash, but the policy server was auto-restarting, and it was only when the disk became full that the outage occurred.
By default the JVM HotSpot JVM 1.7 with the default settings is to produce a mdmp file for each crash. For HotSpot Java 1.7 the setting -XX:-CreateMinidumpOnCrash in JVMOptions.txt will disable producting minidumps on a JVM crash
For JVM 1.7 there is no option to change the directory where it will place the mdmps (JRocket, and Java 1.8 have more options).
