TLS errors

[Hans Schnehl]

Hi, 

I do have a lot of reoccurring entries as following with Tor logging on debug level. 



This is Tor v0.2.0.15-alpha-dev (r13006) but same was happening before with lower versions. 
  Here  is an excerpt:

%tail -f /usr/local/etc/tor/debug.log | grep error

Jan 02 12:45:57.965 [info] TLS error: <syscall error while writing> (errno=1: Operation not permitted)

Jan 02 12:46:47.523 [info] connection_handle_write(): tls error. breaking.
Jan 02 12:46:56.584 [debug] TLS error: unexpected close while reading

and so on.

Tor is running, but appears to be using only fractions of the bandwidth it is supposed to.
Can someone please give a short explanation?
(for a non-crypto-hacker)
