Description:

CEM: data aggregation ran successfully and tables are created, but on any report, besides today, you cannot search and retrieve stats for other period of time (yesterday, last week, last month, last year). The following warning is seen in the EM log of the collector running stats aggregation:

6/05/13 12:02:09.610 AM PDT [WARN] [DailyAggregation.Thread1]

[Manager.com.timestock.tess.services.processors.StatsAggregator] Bad rowsprocessed: ''

Solution:

Needs to increase ThreadStackSize to 192 (or higher) in tess-default.properties and restart the stats aggregation collector.

NOTE: Please note that ThreadStackSize is on 2 places in this file (oneis for daily aggregation and one for defect aggregation); please increase it to 192 on both places.

This issue affects 64 and 32 bit Java/Linux. It is schedule to be fixed in upcoming release.
