Hi, I'm converting the fm-api init script to be handled completely by systemd, however I'm seeing that, once I created the unit file, pmod is constantly launching fm-api (which causes a failure in fm-api is there is a conflict in the network address usage). So, this is my unit file for fm-api. [Unit] Description=Fault Management REST API Service After=nfscommon.service sw-patch.service After=network-online.target systemd-udev-settle.service [Service] Type=simple RemainAfterExit=yes User=root ExecStart=/usr/bin/fm-api --config-file=/etc/fm/fm.conf PIDFile=/var/run/fm-api.pid [Install] WantedBy=multi-user.target Then I edit the /etc/pmon.d/fm-api.conf file to this: [process] process = fm-api pidfile = /var/run/fm-api.pid service = fm-api.service style = systemd ; ocf or lsb severity = major ; minor, major, critical restarts = 3 ; restarts before error assertion interval = 5 ; number of seconds to wait between restarts debounce = 20 ; number of seconds to wait before degrade clear What I've seen is that pmond is looking for the pidfile, but this is not created as this was done by the deleted init script[0]. Also, according to this comment[1], looking for the pidfile is the last resource but I can see frequent attempts to find this file, see below: $ sudo strace -e trace=file -p 86386 --- SIGRT_2 {si_signo=SIGRT_2, si_code=SI_TIMER, si_timerid=0x20, si_overrun=0, si_value={int=6882944, ptr=0x690680}} --- open("/var/run/fm-api.pid", O_RDONLY) = -1 ENOENT (No such file or directory) --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=3222970, si_uid=0, si_status=0, si_utime=0, si_stime=0} --- --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=3222617, si_uid=0, si_status=0, si_utime=0, si_stime=0} --- --- SIGRT_2 {si_signo=SIGRT_2, si_code=SI_TIMER, si_timerid=0x20, si_overrun=0, si_value={int=6882944, ptr=0x690680}} --- --- SIGRT_2 {si_signo=SIGRT_2, si_code=SI_TIMER, si_timerid=0x20, si_overrun=0, si_value={int=6882944, ptr=0x690680}} --- --- SIGRT_2 {si_signo=SIGRT_2, si_code=SI_TIMER, si_timerid=0x7efa, si_overrun=0, si_value={int=6853136, ptr=0x689210}} --- --- SIGRT_2 {si_signo=SIGRT_2, si_code=SI_TIMER, si_timerid=0x20, si_overrun=0, si_value={int=6882944, ptr=0x690680}} --- open("/var/run/fm-api.pid", O_RDONLY) = -1 ENOENT (No such file or directory) --- SIGRT_2 {si_signo=SIGRT_2, si_code=SI_TIMER, si_timerid=0x7ed1, si_overrun=0, si_value={int=6883584, ptr=0x690900}} --- Does anybody know what can be causing this behavior ?
