Hi,
I have a mirroring setup in which
S1 is principle
s2 is mirror
s3 is witness
there are 7 databases that are mirrored between S1 and S2,
suddenly today I found that the DB1 on S1 went into retoring mode though it was still acting as principle. The failover didnot happen.
due to this the whole site for the database was down.
When I see the error log I see the following
The mirroring connection to "TCP://<Witness Server>2" has timed out for database "DB1" after 10 seconds without a response. Check the service and network connections.
During this time there was high CPU Utilization in the range of above 95% for the server containing the principle datbase.
I am not able to conclude on, what could be the reason for this timeout, I dont think it was because of the network connection for the witness server.
Please let me know, waht could be the possible reasons for this issue.
Could it be
1: n/w connection OR
2: High CPU utilization
OR anything else that can be though of
Also please note the issue happened only for one database out of all the 7
Also I notice that one of the Jobs on the DB1 db is taking very longtime and when ever it is excuting the CPU utilization is high... could this be the potential reason for the connection timeout--> then DB1 going into restoring mode ?
