Dear All,
I have been running GNURadio fairly constantly for a
couple of weeks now using simple_ra although, I don't believe it is a
problem with that application as HTOP doesn't indicate memory issues etc.
I run GNURadio version 3.7.9.1 on an Intel® Core™ i7-2600
CPU @ 3.40GHz × 8.
I have been running Ubuntu 14.04 LTS for years now but on
encountering the issue recently with continuous GNURadio use, I upgraded
to 15.10 but the problem still occurs.
Here is what they syslog(s) say:
previous (for years!) 14.04LTS

I get no other symptoms i.e. no D's or anything bad
reported by UHD.
I also don't get problems with any other applications to
indicate some memory issue though I wouldn't expect the regular apps to
use as much memory - mind you when running simple_ra uses less than 10%
of the memory.
Any ideas on how I can narrow the cause down?
Kind Regards,
John
