Comment (by andrii.grytsenko):
Hi,
The problem is still exist, but now even worse, because every now and then
child process is killed by parent and has not been re-spawned back.
{{{

port is 08 is not listened
{{{

and only parent process is running
{{{

}}}
when stracing parent process it's doing nothing but waiting for some
external event or something:
{{{
strace -f -p 20918
Process 20918 attached - interrupt to quit
poll([{fd=6, events=POLLIN}], 1, -1
}}}
