Too resource hungry

Reported by: myopenid Owned by: ioerror
Priority: Medium Milestone: Tor: unspecified
Component: Core Tor/Tor Version: Tor:
Severity: Normal Keywords: tor-relay memory cpu resource
Cc: Actual Points:
Parent ID: Points:
Reviewer: Sponsor:


After a few hours of running Tor it uses up all CPU cycles and unusual amount of memory, in the range of 120Mbytes, regardless of traffic condition, which is, at the time of observation 1Kbytes/s.

It is running on Ubuntu 12.10 VPS, and is configured to run as an exit node.

Once the log showed "Error creating network socket: No buffer space available
", even though there is still 300Mbytes of free memory.

Now, attempt to restart, reinstall Tor does not solve the problem.

Are recent 0.2.4 versions any better here?

What kind of a configuration is this?

Have you tried using 'perf' or 'oprofile' to see where Tor is spending its time?

It might also be a good idea to ask on the tor-relays mailing list whether other people have seen similar issues, and if so what they did to solve them.
