Process hangs on Solaris

[joerg.bruennert/sy/rbg/<de...@rb...>]

Hello,

i have only one (simple) question.
With my ucd-4.2.1agent i can controll
processes if they run or not.
but yesterday the notes process are
in my process list and snmp agent
don`t display any error but the notes
process hangs. I must restart it.
So my question is if it is possible to
detect hanging processes ?

Thanks for helping me

Joerg
