[OpenSIPS-Users] failed to process sync chunk warnings when doing dr_reload

[Kingsley Tart]

Hi,

I have a 3 node cluster running OpenSIPS 3.1.5.

If for example on node 1 I do a dr reload on the command line like
this:

# opensips-cli -x mi dr_reload
"OK"
#

I suddenly see a load of warnings in opensips.log:

On this particular occasion, node 2 didn't log anything, but the
following was logged on node 3:

Oct 22 18:25:06 ipx-c /usr/sbin/opensips[21267]:
INFO:clusterer:handle_sync_request: Received sync request for
capability 'drouting-status-repl' from node 1, cluster 1
Oct 22 18:25:06 ipx-c /usr/sbin/opensips[21267]:
INFO:clusterer:send_sync_repl: Sent all sync packets for capability
'drouting-status-repl' to node 1, cluster 1


OpenSIPS had been running for at least 15 minutes on all nodes before I
did the dr_reload.
This is the drouting config in opensips.conf:

loadmodule "drouting.so"
modparam("drouting", "db_url",
"mysql://XXXXXXXX:XXXXXXXX@localhost/opensips")
modparam("drouting", "probing_reply_codes", "405")
modparam("drouting", "probing_interval", 15)
modparam("drouting", "use_partitions", 1)
modparam("drouting", "db_partitions_url",
"mysql://XXXXXXXX:XXXXXXXX@localhost/opensips")
modparam("drouting", "db_partitions_table", "dr_partitions")
modparam("drouting", "cluster_id", 1)
modparam("drouting", "cluster_sharing_tag", "vip-
a")                    # } The sharing tag on these two lines MUST
match
route[get_drouting_cluster_sharing_tag] { $avp($param(1)) = "vip-a";
}  # }


Node 1 had the vip-a sharing tag active on it when I did the dr_reload.

Each node has its own local DB. I had not updated the DB rules on the
other nodes just yet, so they would have differed.

Any idea why I'm getting these warnings?

Cheers,
Kingsley.
