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 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,
