    MCOL-445: Modify getConfig and setConfig to be case insensitive on variable names.

problem related to system status initialing setting, which is set to DOWN = 9, and the stop in main.ccp that reads and checks the status to determine if it needs to launch processes, which is shown here

main.cpp:736 if ( systemstatus.SystemOpState != MAN_OFFLINE && !DISABLED) {

At the time line is hit, the system status = MAN_OFFLINE (0). It should be DOWN (9).

System and Module statuses

Component Status Last Status Change
------------ -------------------------- ------------------------
System MAN_OFFLINE

So need to see why its not DOWN

-----------------------------------

Breakpoint 1, main (argc=1, argv=0x7fffffffe648) at /home/builder/mariadb-columnstore-server/mariadb-columnstore-engine/procmon/main.cpp:736
736 if ( systemstatus.SystemOpState != MAN_OFFLINE && !DISABLED) {
Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.209.el6_9.2.x86_64 libgcc-4.4.7-18.el6.x86_64 libstdc++-4.4.7-18.el6.x86_64 libxml2-2.7.6-21.el6_8.1.x86_64 zlib-1.2.3-29.el6.x86_64
(gdb) p systemstatus.SystemOpState
$1 = 0

ok,this explains it.. the thread that is setting up the shared memory and setting the initial settings to DOWN is taking place after the main.cpp code, where it got launch is making the call to get the status... Code has a sleep of 6 seconds to allow the shared memory to be completed, but that is not long enough.
So either need to increase the sleep or better yet, need to set a initial flag where main will continue once the shared memory has been initialization.

pull request is done, please review.

Code change, replaced a sleep with a resume main thread flag to resolve problem

to test, should be done on a centos 6.9, but fix wasnt really specifically related to 6.9.problem was a timing issue..

Just perform a binary install and run postConfigure for a single-server install and make sure postConfigure completes and system is ACTIVE.

Closing this issue as it was released months ago and slipped through the cracks.
