Running TOR



Hello all,

   [note: I'm posting this to NetBSD's pkgsrc-user mailing list, as well
as the TOR talk mailing list]

   I'm trying to run tor v0.1.1.22 on NetBSD/amd64 3.0. I'm running it
as an exit node. It does seem to run pretty fine, but only for a while.
I noticed that it does consume *vast* amounts of RAM, and after a while
it has consumed so much that it starts eating off the swap, and finally
I get messages which state that TOR processes are being killed off for
eating up the remaining swap.

   This is an except from "top" (yes, I am aware of that "top" isn't
optimal for memory related detective work).

  PID USERNAME PRI NICE   SIZE   RES STATE      TIME   WCPU    CPU COMMAND
 1535 tor        2    0    38M   23M netio      0:00  0.00%  0.00% tor

 1823 tor        2    0    38M   23M netio      0:00  0.00%  0.00% tor

 1716 tor        2    0    38M   22M netio      0:00  0.00%  0.00% tor
 1688 tor        2    0    38M   22M netio      0:00  0.00%  0.00% tor
 1198 tor        2    0    38M   22M netio      0:00  0.00%  0.00% tor
 1150 tor        2    0    38M   22M netio      0:00  0.00%  0.00% tor

   I'm not really sure how an application which relays TCP traffic
(albeit encrypting/decrypting it) can consume this amount of RAM. Is it
really normal?

   What's worse... A few times NetBSD has hung, *completely* (requiring
hard reset), when TOR has consumed all memory. I have never has NetBSD
crash hard on me before as far as I can remember. Since I started
running TOR a few days ago, I have had several total crashes.

   Is anyone else having problems with tor and memory consumption? On
NetBSD?
