Rasmgr was killed after multiple error queries

[Bang Pham Huu]

Import the test collection (sdom: [0:221,0:177]) from ​http://rasdaman.org/browser/systemtest/testcases_services/test_all_wcst_import/test_data/wms_4326

Then run this command in a bash file to kill rasmgr:

for i in {1..200}; do 
    rasql -q 'SELECT ENCODE(Scale( Extend( ( ( c0[-1000:221,200:277] ) ), [-1000:221,200:277]), [0:599, 0:599] ), "png", "") FROM test_wms_4326 as c0' &
done

The error from the query is:

ERROR] - 2018-06-06 10:32:51,513, /home/rasdaman/rasdaman_community/tmp/rasdaman/raslib/sinterval.cc:228: 
Invalid interval: lower bound (0) is greater than the upper bound (-1000).

after that rasmgr is killed and cannot connect from rascontrol

I can't reproduce with two rasservers, after a while all queries finished and the rascontrol result is

$ rascontrol -q -x "list srv -all"
