They are Threads, please see my Explanation from the old Honksbot Forum:
Q: I dont understand why my hlds server spawns up to five processes
each one take more than 50mb of memory
A: Youre wrong. They are no Processes, they are Threads. The fifty MB each
of those Processes is showing up in 'top' is shared - thus, they are only
consumed ONCE, but showed up on every Process. You can calculate it through.
Mine for example show 5*150MB (what a hog!). These are 750 MB. The System
has 1 GB of RAM and 500 MB of Swap. There is almost 1Gig RAM and 30 MB Swap
used. For the Easyness say its 1GB used. Now there are 655MB cached (thats
the harddisk Caches in RAM). 1Gig - 655 MB makes 345 MB. So to get the hlds
Process for 750 MB the other Processes would need to take -405 MB? As you
know, no Process can take up negative Memory (Oh, RAM would be soooo cheap)
BTW, thats the very same Behaviour you see with Other multithreaded Deamons,
for example Apache.
Likewise, the Behaviour your Machine shows is very normal. Its the Bot
spawning 4 Threads, so it can enqueue Date in one Thread whilst queueing
it to IRC via another. I cant exactly remember the other two Threads, i
had to dig through the source again. However, this Threading is
necessary. Your Bot would flood himself off of IRC if that Queueing via
Threads wouldnt be done.
