sql server notification services : Notification Services stability and consistency

Hi,

I am using notification services on my accounts table to notify
upwards of 8-10 subscribers of any changes, and what seems to happen
is the following:

- approximately 90% of the time everytime runs great, no problems,
speedy results from the db (sql server 2005)
- the remaining 10% will see timeouts on queries touching the accounts
table

My deployment is as generic as possible, using all default values. As
I am historically a sysadmin temporarily playing the role of a DBA, I
was hoping someone here could provide an answer or an URL which
discusses this type of problems in more depth. If I did not supply
enough information, please let me know what info to get and I will do
so to the best of my ability.

TIA!

It sounds like the query which is checking for events gets blocked
because another query on the system is locking the rows needed. You
may want to check out the activity monitor and look for deadlocking
processes as well.
