strace gst-remote --pid produces this:

open("/etc/hosts", O_RDONLY|O_CLOEXEC)  = 4
fcntl(4, F_GETFD)                       = 0x1 (flags FD_CLOEXEC)
fstat(4, {st_mode=S_IFREG|0644, st_size=1537, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 
0x7f85614d6000
read(4, "# /etc/hosts: Local Host Database"..., 4096) = 1537
close(4)                                = 0
munmap(0x7f85614d6000, 4096)            = 0
rt_sigprocmask(SIG_BLOCK, ~[QUIT ILL ABRT BUS SEGV RTMIN RT_1], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, ~[QUIT ILL ABRT BUS SEGV RTMIN RT_1], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, ~[QUIT ILL ABRT BUS SEGV RTMIN RT_1], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
mprotect(0, 4096, PROT_READ|PROT_WRITE) = -1 ENOMEM (Cannot allocate memory)
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0
tgkill(7152, 7152, SIGABRT)             = 0
--- SIGABRT (Aborted) @ 0 (0) ---

So somewhere it looks like gst is running out of memory.

NB: Looking at the trace file made me wonder

        $ grep localtime gst-rem.log | wc -l
        715

Why does gst-remote check /etc/localtime *that* often?

Curious,
