I don't know if this problem has been already solved (i didn't find
anything neither here nor when searching with google) but I'm posting
it, maybe someone will save some time...
I don't know if that's the same issue that others here were experiencing
but it looked exactly the same. Anyway, I thought that posting this wouldn't
hurt ;)
The problem on my FreeBSD 4.8-REL was caused by /dev/null being chmod 600!
That's a strange thing, it "happened" only on one of two 4.8-RELEASE
(the one cvsupped about three weeks ago, the other about a week ago)
I have access to and not on my 4.8-STABLE.
After changing it to 666 deliveries are being run as scheduled.
From exim.c:
/*************************************************
* Ensure stdin, stdout, and stderr exist *
*************************************************/
[ some more explanatory comments ]
void
exim_nullstd(void)
{
int i;
int devnull = -1;
struct stat statbuf;
for (i = 0; i <= 2; i++)
{
if (fstat(i, &statbuf) < 0 && errno == EBADF)
{
if (devnull < 0) devnull = open("/dev/null", O_RDWR);
if (devnull != i) dup2(devnull, i);
}
}
if (devnull > 2) close(devnull);
}
So when exim was started in foreground with output on stdout/stderr
everything was alright, but when it was run in background spawned processes
had fds 0, 1 and 2 closed which apparently (I didn't have time to investigate
further) caused problems.
