Hello,

Hello Udo,

I've opened https://trac.torproject.org/projects/tor/ticket/27750 with this
problem.

Quickly like that, I can't tell you why this is happening or any workaround
you could do so keep an eye on the ticket. If this is an 0.3.4.x regression,
we'll find it quickly.

Thanks!
David

Issue is still happening, with just port 22 and 53 open.
What can I do to help fix the issue?

If this is easily reproducible, and you can build from source, using
"git bisect" to find the first version that caused it would be very
helpful. Do you want more info on how to do that?

0.3.5.3-alpha has an issue very much like the original issue I reported
here, despite being patched for that.
The OoM situations appear to have been fixed but I need more time to be
sure.
