Hi,

I'm using yafu 1.09 mt and I (still) found zombie processes.

This time it's not after a crash. My steps:
1 - I pause all project except Yafu to force Yafu to run.
2 - After some times I resume others projects
3 - => A running Yafu WU is paused (time near 10 min)
...
4 - Next day, goto step 1
5 - The Yafu WU is restarted from zero

When I perform a PS I found zombie process in pause

A valid yafu process look like this:

Everything is under /usr/bin/boinc

Yafu is no more under boinc, it's a standalone program.

Hope his help
