[Cflowd] cfdcollect stops working

[Christian Cinetto]

Hi,  I have been running Cflowd for one month on two  routers Cisco 75XX.
I ran cflowdmux, cflowd , cfdcollect on the same dedicated machine, with 
the following configuration:
OS:Linux Red Hat 7.2; proc. Pentium III 600 MHz, RAM 1 GB;
The arts files started to be  created without problems for 24-32 hours, 
then cfdcollect stopped without any log message; when the process stops,it 
generates a huge core file located in /usr/local/arts/etc (where the 
.conf files are located); cflowdmux and cflowd behave normally.
The current software installed :
cflowd version 2-1-b1 ; arts 1-1-a8.
I tried to stop the processes and to start them back again; the behaviour 
is more or less the same,i.e. after a while cfdcollect stops again.
I would appreciate any suggestion,
thanks
