We have had a problem in our production environment where the number of 
reserves for a job is hitting a limit (in our case 10) and the job is being 
buried.

However, it now appears that the first time we reserve the job, from our 
application, it already has a reserves value greater than 10.

We monitored tcp traffic with the following.

/usr/sbin/tcpdump -n -l lo -s 16436 -w /tmp/bt.dump port 11300

We see the following in the output.

INSERTED 1234
stats-job 1234

id: 1234
tube: my_queue
state: ready
pri: 10000
age: 0
delay: 0
ttr: 120
time-left: 0
reserves: 0
timeouts: 0
releases: 0
buries: 0
kicks: 0

RESERVED 1234 1051

stats-job 1234

id: 1234
tube: my_queue
state: reserved
pri: 10000
age: 10
delay: 1
ttr: 120
time-left: 119
reserves: 11
timeouts: 0
releases: 10
buries: 0

So, the question I have is, why is there a reserves of 11 by the time our 
application does the initial reserve call?

I would have expected that reserves is only incremented whenever our 
application makes the call to reserve?

Or are we miss-using this field?

Note. We are running beanstalkd-1.4.6-2.el5 (because that is the latest 
packaged version we can get)
