[SR-Users] "kamctl fifo debug" does not work

[Klaus Darilion]

root at pbx-kam-1:/home/klaus3000# kamctl fifo debug
DEBUG:: 2

root at pbx-kam-1:/home/klaus3000# kamctl fifo debug 0
DEBUG:: 0

[cfg/cfg_ctx.c:411]: INFO: cfg_set_now(): core.debug has been changed to 0

but:

root at pbx-kam-1:/home/klaus3000# kamctl fifo debug
DEBUG:: 2


Is this a bug?
