I'm having problems with clients not reconnecting if I restart the
rrdcached daemon. For example, collectd prints out the following type of
error forever if I do a "service rrdcached restart" (using unix socket,
but I believe same happens with TCP):
Oct 30 05:03:52 sketchy1-1b collectd[3551]: rrdcached plugin:
rrdc_update (/rrds/.../memcached_command-set.rrd,
[1256878677:2904863359], 1) failed with status -3.
I believe this comes from rrd_client.c in response_read:
buffer_ptr = fgets (buffer, sizeof (buffer), sh);
if (buffer_ptr == NULL)
return (-3);
chomp (buffer);
Seems to me that this is to be expected:
"gets() and fgets() return s on success, and NULL on error or
when end of file occurs
while no characters have been read."
The proper error handling to close the connection seems to be missing?
