ptpd status file not updating

[Andrew Thomson]

Hi,

I'm noticing this happens on a number of hosts, seemingly randomly, all Ubuntu 18.04.

Running this package:

ptpd 2.3.1-debian1-3 amd64

Ptpd stops updating it's status file:

pub03:~# ls -l /var/run/ptpd.status
-rw-r--r-- 1 root root 1362 Jul 3 17:45 /var/run/ptpd.status
pub03:~# date
Wed Jul 3 20:35:01 CDT 2019

I also observe higher CPU usage, and an strace seems to indicate some kind of continuous loop??

--- SIGALRM {si_signo=SIGALRM, si_code=SI_TIMER, si_timerid=0x1, si_overrun=47, si_value={int=-1710448416, ptr=0x56079a0ca0e0}} ---
rt_sigreturn({mask=[]}) = 0

rt_sigreturn({mask=[]})

Any ideas?

Thanks!
