How to solve the huge HTTPRL error that fills down all of Cron \ Status report? Background

For some time now, and only in some occasions, when I run CRON (Status report), I see a huge error (About 170 rows) at the HTTPRL section (related to the HTTP Parallel Request &amp; Threading Library module). It happens randomly - Sometimes it happens and sometimes it doesn't. When the error does not appear, the HHTPRL "section" in status report is all green. Here is a screenprint of it:



What I already tried

I've tried to play a bit with the HTTPRL preferences, but nothing really helped... For example, tried to change at "IP Address to send all self server requests to": from -1 to 1. Also tried to uncheck "Enable background callbacks", But IIRC nothings has changed.

The only changes I saw (When the error was apparent) were when I unchecked "Enable background callbacks", or otherwise, when I check-marked "Use httprl to handle drupal_http_request" --- When I ran Cron afterwards the error's text went from about 170 rows to 90 rows. But this data doesn't help me to understand Why the error was there on the first place and even worse - Why it appears randomly?

Bottom line

Is this a known problem? You might have an idea why this happens or a tip how to try to solve it?
The solution (or at least work around?) could be what is described in Comment # 8 of Issue # 2450725 related to the HTTP Parallel Request &amp; Threading Library module:

change &quot;'timeout' =&gt; 7,&quot; to &quot;'timeout' =&gt; 1,&quot;
This timeout is used in lock_acquire() that probably locks Drupal for 7 seconds, but in httprl config httprp waits only 5 seconds for a response.

Comment # 17 in that issue also contains a corresponding patch, which looks like so:
