| Summary | 0005532: Auto-analysis freezes MM / Triggers AV on upgrade from 3.0 DB to 3.1 DB | ||||
| Description | In some circumstances, the process of upgrading the DB from 3.0.6 to 3.1 seems to trigger either a freeze in MM, or endless AVs. Repro steps: Rename a 3.0.6 db into MM.DB Install 3.1 Run 3.1 -->DB upgrade proceeds -->File monitor starts -->Either the file monitor freezes, or many AVs start occuring (though sometimes it proceeds without a problem) Note: in current tests, filemonitor and auto-analyze are enabled. I'll check if disabling auto-analyze has an effect. | ||||

Further testing shows that the DB upgrade actually proceeded properly and the problem is actually related to concurrent running of the File Monitor and Auto-analysis. Tested as follows. 1) Performed DB upgrade from 3.0.6 to 3.1 2) Enabled file monitor and auto-analysis in MM 3) Re-ran MM --> AV Note: I tested the file monitor standalone (no auto-analysis) and it triggered no errors. Will test if standalone usage of auto-analysis triggers the problem. |

Another update: When I test with only auto-analysis enabled, the AV still occurs. Thus the problem seems to be an auto-analysis issue. tested as follows: 1) Set MM 3.1 with File Monitor disabled, and Auto-analysis enabled 2) Closed MM and configured MM 3.0.6 db to be used 3) Ran MM -->DB upgrade occurred -->Auto analysis didn't run! 4) Closed MM and ran MM -->Auto analysis started and AV occurred Strangely enough, if I disabled auto-analysis and performed a manual analysis, there were no errors. |
