[rabbitmq-discuss] Slow startup/recovery time

Tue Aug 2 12:37:10 BST 2011

Hi,

Since upgraded to 2.5.1 from 2.1.1, one of our rabbit servers refuses to
finish startup procedures.. starup_log shows:

At this point it keeps 'doing nothing' forever.. which makes me think it's
just re-indexing/recovering queues and messajes, however, the mail log files
show the following error:

=ERROR REPORT==== 2-Aug-2011::13:27:55 ===

                           {submit_async,

               {message_properties,undefined,false},
               true},
              no_del,no_ack}]},
        {rabbit_queue_index,'-journal_minus_segment/2-fun-0-',4},
        {array,sparse_foldl_3,7},
        {array,sparse_foldl_2,9},
        {rabbit_queue_index,'-recover_journal/1-fun-0-',1},
        {dict,map_bucket,2},
        {dict,map_bkt_list,2},
        {dict,map_bkt_list,2}]}

Should I ignore such error??

PD: I can zip & send our mnesia files just in case they are needed to debug
the issue.
