Hello Bill,

this behaviour had been discussed here, I think:

https://dev1galaxy.org/viewtopic.php?pid=11522#p11522

In that thread and others on that forum there are a couple of links to 
other threads etc. about this issue.

The proposed solution is a patch which originated here:

https://bugs.devuan.org//cgi/bugreport.cgi?bug=237

…which I have applied on my system (devuan/ascii) and never seen this 
problem again.


HTH,

Kind regards,
Stefan
