2289524 - Error 2 opening /proc/22505/lwp/71/lwpusage - SAP ASE

• While performing RPCs via CIS from ASE to IQ to store MDA monitoring data. Error 2 opening /proc/22505/lwp/71/lwpusage
• The process could not be killed
• Run to completion task 'CtlibController' exiting.  The RTC Task that died was the CtlibController.
• During this process, the spid was hanging both on IQ and ASE side and were not responding to kill requests. 
• The IQ server was killed.  This in turn resulted in ASE's CtlibController to get a signal 11.  Subsequent calls to monThread shows failure in accessing /proc/pid/lwp/thread/lwpusage.
• It also received a signal 11
