--- Comment #2 from Henry Hu <henry.hu.sh at gmail.com> ---
I can't reproduce this since those IPs are not blocked here. Can you try to
grab a stack trace of the busy thread?
A possible way to do this:
> pgrep telegram
<telegram pid>
> ps auxH -o lwp | grep <telegram pid>
<list of threads>

Here, you can find the thread which is consuming 100% cpu. The thread id is
listed as the last column.
Then, run gdb
> attach <telegram pid>
> thread <thread id>
> where

This will give you the backtrace of that thread. This may help in diagnosing
the problem.

Also, you may report a bug to upstream:
https://github.com/telegramdesktop/tdesktop/issues

Finally, you may run telegram under ktrace, to find out if telegram is busy
calling some system calls, etc.
