# About error ER_CON_COUNT_ERROR:
# - this error is associated with SQLSTATE 08004,
# and returned from 2 places in the server code.
# - which path returns the error is not predictable,
# as it depends on the server load and thread scheduling
# - one path returns a SQLSTATE of 08004
# - another path returns no SQLSTATE at all,
# and then the client sets a default value of HY000 for SQLSTATE
#
# Testing for error ER_CON_COUNT_ERROR alone causes this to
# be printed in the result file:
# - ERROR 08004: Too many connections
# which in turn causes spurious test failures.
#
# To work around this, this scripts expect to see either
# the error number ER_CON_COUNT_ERROR (it always does)
# or the error number 9999 (it never does, this error does not exist).
# The exact error number and SQLSTATE is not printed in the result file,
# makig this test robust for both cases:
# - ERROR 08004: Too many connections
# - ERROR HY000: Too many connections
