I had a similar problem with the talkd too, lots of sleeping processes,
putting my load up to 20....
But I got them killed, the problem of unkillable processes happened with a
overloaded postgres process having the flag D (from the ps man page: D for
uninterruptible sleep), I had to reboot the machine to get rid of those
process, since theyre presence inhibited ohter prostgres incarnations....

seems not, read the ps man-page, but why should such process exist and how
get rid of them without rebooting?

Those blocked processes had an impact on my system, blocking virtual memory
and PID's (my users are busy, and we work on parallel execution, means lots
of concurrent processes). Machines are 486DX2-66, bi-proc 586-90, elf, linux2
