Issue: when trying to do a vMotion they get an error about the ramdisk being full.

kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2001550
checked for the wtmp but did not find it.
What worked :
Download and install "HP Agentless Management Service Offline Bundle for VMware ESXi 5.x"

Why :
To avoid filling the RAM disk, AMS is now creating its log file “hpHelper.log” in the configured scratch location (default of /scratch/log directory).  In addition, a soft link to the log file is created in the path /var/log.  The hpHelper.log file may grow to a maximum size of 10MB and a file rotation algorithm has been implemented with support of up to 10 archived hpHelper.log files.
