Subject [jira] [Commented] (APLO-284) Invalid log position warnings
Date Mon, 25 Mar 2013 08:27:17 GMT

    [ https://issues.apache.org/jira/browse/APLO-284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13612462#comment-13612462

Lionel Cons commented on APLO-284:
----------------------------------

FWIW, I have upgraded to apollo-99-trunk-20130322.033735-216 and the problem is still present:
 - the broker logs "detected store dropped message"
 - for one dsub, the broker does not send messages although there is a consumer waiting for
them
 - the dsub does have a registered consumer (consumer_count=1)
 - the consumer connection does exist but it has (waiting_on='client request'), looking at
the write_counter, Apollo just sends heart-beats (i.e. single bytes)
 - after restarting the consumer, some messages get sent (the most recent ones) but others
stay in the dsub (queue_items'=25507 and this does not decrease)

> I don't know if this is related to APLO-176 but on a broker running apollo-99-trunk-20121221.031630-148
we see many (>1k) warnings like:

> 2013-01-07 10:02:55,942 | WARN  | Invalid log position: 122526752423 | 
> Does this indicate some kind of data store corruption?
