sql server replication : Agents hang on failure

Transactional Replication

Publisher in Hong Kong, distributor in Calif - subscriber in Calif

LogReader & Distr. agents on 2 minute schedule.

Connectivity lost to remote publisher, the Log Reader (job) gets to Step 3:
Detect nonlogged agent shutdown. In Replication Monitor the Log Reader agent
displays 'Performing completion actions'.

The only option is to 'Stop Agent' - however it never stops, even after
hanging for 8 hours+ in this state - I never get the option 'Start Agent'
enabled.

I try to stop/start on Log Reader job itself - and nichts.

The only way to resolve, stop & restart SQL Services on distributor.

Any ideas how or why this is happening?

TIA,

Log reader agents should run continuously as opposed to a scheduled basis,
also you should have local distributor - you shouldn't connect to a remote
distributor over the WAN.

Chris,
you could enable logging of the log reader to try to get more info:
http://support.microsoft.com/?id=312292
It could be that the transaction log is huge and it is taking ages to read
through it. It could be that there is some blocking in the distribution
database which is stopping the log reader from completing (sp_who2 will give
info on this).
