[Freeswitch-users] [freeswitch] <defunct> when using cmd="exec" in freeswitch.xml

[Mitja Thomas]

Hi Micheal,

yeah I think your workaround will work fine and Ill change it that way. 
But this issue might still be a missbehaviour. Either by fs in which 
case I think it might be an interesting information for the Developers 
OR a wrong usage by me in which case this is an interesting information 
for me :)

Thanks,
Mitja
