Environment

Sentinel 7.4 Report

Situation

Client is unable to run a report called "Sentinel Core Event Count Thread."   If  it is run on a daily basis (CRITERIA: Previous Day) and after a few days of running, it would eventually fail.  The report would only run successfully if criteria is set for 2 hours. Anything more than that, it fails.

The error I see in the log:

Resolution

Upgrading to Sentinel 7.4 SP4 resolves this issue or a private patch can be applied.
