Issue/Introduction

We are preparing on updating to 9.02 from 8.51
When we restart the robot service we found that that hard drive was filling up.
When you look into it further, most of the java probe such as discovery_server, udm_manager, wasp were generating java memory dumps continually filling up the drive.

from the java hs_err_pidXXX.log
Stack: [0x0000000000f50000,0x0000000001050000],  sp=0x000000000104e2a0,  free space=1016k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)
V  [jvm.dll+0x13e613]
C  [sqljdbc_auth.dll+0x6857]
C  0x0000000001247f54

Cause

the <nimsoft>\lib folder had multiple sqljdbc_auth.dll files that had been renamed.
A directory of the lib folder showed the following:
 Directory of D:\Program Files (x86)\Nimsoft\lib

03/07/2018  01:32 PM           103,480 sqljdbc1_auth.dll
04/17/2020  02:08 PM           300,112 sqljdbc_auth.dll
02/16/2018  06:02 PM           299,088 sqljdbc_auth_1.dll

Environment

UIM 8x,9.x,20.x

Resolution

stop the robot service.
remove all but the correct version of sqljdbc_auth.dll from the directory.
for UIM 8.x the size is 103,480 
for UIM 9.x, 20.x the size is 300,112
clear up all of the java crash files
start the robot service.
