[srobo-devel] Pylint processes not joined in IDE

[Jeremy Morse]

Hi,

Tyler's monitoring scripts have squawked a bit about the number of
zombie processes on saffron; I figured this was because there were some
httpd workers waiting to be reaped. On closer inspection however, at
this moment there are four pylint processes in a semi-permanent zombie
state. They have not been joined to their parents, and have been alive
for at least 3 minutes, so are not going to be. In pstree:


├─httpd─┬─7*[httpd]
│ ├─2*[httpd───pylint]
│ ├─httpd───2*[pylint]
│ └─2*[httpd───27*[{httpd}]]

(The 27 httpd's at the bottom are going to be wsgi contained threads).

The cost of these processes hanging around is negligible but nonzero;
they should definitely be joined. Otherwise they'll sit there until the
httpd worker process is exhausted and get join'd back to the master
httpd process. I've opened #2992 to track this.
