Hello,
the redis commands have relavance, by the os.execute() likely does it,
seems to use c function system() which calls fork().
You should try to use KSR.exec.exec_cmd("..."), this has been used in
kamailio for many years. Btw, be sure you check the parameters/values
you give to the shell commands to avoid troubles, if you simply get them
from the untrusted parts of the sip message.
Anyhow, at the end the issue is a conflict because signal handling and
syslog(), probably it needs to be reviewed a bit for such cases.
Cheers,
Daniel
