I did an experiment to try to simplify the problem, and rule out mqueue
concurrency/locking issues:
modparam("pv", "shvset", "lasttm=i:-1")
modparam("rtimer", "timer", "name=test;interval=1;mode=1")
modparam("rtimer", "exec", "timer=test;route=TEST_ROUTE")
route[TEST_ROUTE] {
while(1) {
if($shv(lasttm) < 0)
$shv(lasttm) = $TV(sn);
else {
$var(gap) = $TV(sn) - $shv(lasttm);
if($var(gap) >= 1) {
xlog("L_INFO", "Presented time gap:
$var(gap)\n");
}
}
$shv(lasttm) = $TV(sn);
}
}
And here's what I saw in the log:

When I repeated the experiment with interval=3:

So, something is definitely interrupting the possibility of continuous
execution of these rtimer tasks.
