Slow upgrade from 4.2.3 to 4.3.1 which may crash

Matthew Stublefield September 18, 2012

In the course of a test-upgrade, it appears that a process is running that relates to the new personal task list feature. Here is a sample from the logs:

2012-09-19 13:21:06,303 INFO main confluence.upgrade.upgradetask.UserIndexingUpgradeTask doUpgrade Created 28980 from 43108 missing Personal Information objects.

2012-09-19 13:21:15,991 INFO main confluence.upgrade.upgradetask.UserIndexingUpgradeTask doUpgrade Created 28990 from 43108 missing Personal Information objects.

When the process began, multiple groups of 10 were processed per second. By the 8000s, it was taking ~4 seconds for a group of 10. At this stage, a group of 10 takes about 9 seconds.

We only have about 1800 user accounts on the system, but since I'm not quite sure what's going on here, I'm wondering if there's a way to either have it not do this process or to do it more efficiently. Perhaps it is trying to pull in all LDAP accounts? I suspect it will crash at some point since it keeps getting slower, but even if it doesn't, I don't know that I will be able to perform the upgrade within the maintenance window I have.

Any suggestions or guidance would be greatly appreciated. I would like to know exactly what Confluence is doing here and what we can do to speed up the upgrade.

Hi Matthew.

This is a known issue of Confluence 4.3.1: CONF-26742. This issue was resolved in Confluence 4.3.2. I recommend you to try with that version instead.

While this inexplicably took forever on the test system, on production it finished quickly and cleanly.
