plotman kill error - double free or corruption (out)

[flmst]

Hi, I'm getting the following error when trying to kill a job:

(venv) [root@ceph206 fd]# plotman kill a0402a68
Namespace(cmd='kill', idprefix=['a0402a68'])
Pausing PID 7276, plot id a0402a680c5f1e8d58937ac344bea92c53aab6fb4eef8c36f67cf904161242f8
Will kill pid 7276, plot id a0402a680c5f1e8d58937ac344bea92c53aab6fb4eef8c36f67cf904161242f8
Will delete 131 temp files
Are you sure? ("y" to confirm): y
double free or corruption (out)

Aborted (core dumped)
(venv) [root@ceph206 fd]#

After running the command the job is suspended (STP) but the process is not killed and the files remain.
Any ideas?
