Hi,
We recently faced the following problematic situation since we switched on brand new 64 cores / 500GB servers:
- Service broker frozen for all local activites
- Service broker for external servers were still functionnal
- One queue monitor in state "DROPPED" (sys.dm_broker_queue_monitors)
- Thousand lines with weird characters (unreadable ASCII chars)
- every incoming messages were stacked into sys.transmission_queues
- queues where empty
- Active tasks looking frozng were not receptive to KILL actions (sys.dm_broker_activated_tasks)
- Same load, same code on 16 cores servers did never encounter this problem
This was looking like corrupted memory situation and the only solution was to FAILOVER our servers.
Is one of you aware of such a behavior or efficient ways to troubleshoot ? I see no explanation of those weird chars into transmission_status column...
Thanks for your feedback.
