FYI.
We had the below issue occur twice in different environments. This might or might not be happening to you, but if it does, you know now...
Starting situation:
Windows 2008 R2 x64 standard edition (EV and SQL server). SQL 2008R2SP2 standard edition, with log-shipping as DR solution (replication). Enterprise Vault 9.0SP4, and DA9SP4
Upgrade DA9SP4 to DA10SP4 - upgrade config-database, upgrade customer-db, verify evbaadmin is ok, verify DA10SP4 client connects ok.
Apply CHF1 for DA10SP4 - upgrade etc. Verify DA10SP4CHF1 client connects ok.
Logoff.
Monitor SQL logshipping. You might see error:
The log shipping primary database PROD SQL SERVER\INSTANCE.xxxEVDACM has backup threshold of 60 minutes and has not performed a backup log operation for 61 minutes. Check agent log and logshipping monitor information.
