Hi,
I have a templated service and socket, for my program.
thou may not be relevant here , socket is written for inetd (ie FD 0 and 1)
the service type is put as "simple" in systemd configuration,
the service spawns many processes in some flows ( fork + execv ) .
the spawned process opens , IPC connection ( normal socket to another system ), the process is killed by systemd.
is this expected?
Strace of the killed process shows
ioctl(4, FIONBIO, [0]) = 0
write(0, "[112] [IpcIO_Recv] (2 4 0x1b335a0 4) [CRYPT]\n", 45) = 45
write(0, "[280] BIO[0x1b32770]:read(4, 5) - socket fd=4\n", 46) = 46
read(4, 0x1b60533, 5) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
--- SIGTERM {si_signo=SIGTERM, si_code=SI_USER, si_pid=1, si_uid=0} ---
+++ killed by SIGTERM +++
Same issue is not seen for flows where fork+ execv is not there ( ie execv flows and one where we dont load any process)
Socket file looks like below :
[Unit]
Description=XXXX
PartOf=my.service
[Socket]
ListenStream=7777
Accept=yes
[Install]
WantedBy=sockets.target
