Hi Peter and all,
We have a serious "threads" issue in WSJT 4 svn 4857, have a look at the "top" display after running on Ubuntu 14.04 x86_64 for a week now: top - 05:34:32 up 31 days, 20:29, 5 users, load average: 0.23, 0.09, 0.07 Tasks: 305 total, 1 running, 304 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.7 us, 0.6 sy, 0.0 ni, 98.8 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem: 7875868 total, 7450088 used, 425780 free, 110280 buffers KiB Swap: 10485756 total, 14080 used, 10471676 free. 4775268 cached Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 25106 alanb 20 0 87.969g 549256 12844 S 2.3 7.0 639:27.51 python3 24049 alanb 20 0 33324 13324 3276 S 1.3 0.2 145:58.80 Xvnc 6352 alanb 20 0 29260 1776 1156 R 1.0 0.0 0:00.35 top 10 root 20 0 0 0 0 S 0.3 0.0 2:30.35 rcuos/2 ---------------------------- WSPR is using 88Gb of Virtual Memory!!!! John Wiseman from the "pcrepeatercontroller" Yahoo group showed me 'the way', fixing my test code and showing, ARM systems are not at fault, in my blues (previous emails). But, you do have to get your "spawn thread", "detepch thread" and "exit thread" in the right order and timing. As I have mentioned before, I'm not a programmer. As an Engineering student, I did Fortran in 1971 on an IBM 7040 (48k of 36bit words, ram, ferrite cores) In 1985 I started to 'fiddle' with "C". We DO have a problem.
