TeamCity/Clearcase UCM problems

Hi,
I am very new to TC and am now the admin. (gulp)
We are using TC 4.5.5 with CC UCM 7.0.1.4 on WIndows 2003 server. Snapshot views are used.
I have been told (but not seen this in the docs) that TC polls the view, attached to an integration stream, for changes. (how?) and then does a cleartool update. TC then copies the source (and more?) to a cache for each build agent - we only have one - where upon the build agent builds the project.
This usually works but occasionally the cache is not updated - the view is updated. This problems happens with a particularly large project.
So now the questions.
Is what I have written correct - can someone point me to the documentation on this?
Does anyone else have this problem with CC UCM?
Is this a recognised problem that is fixed by TC 5.1? We do have this on Windows 2008 and CC 7.0.1.6 but I have been told there are problems with this - I need to investigate for myself.
Regards,
John

Hi,

You can try to restart your server with "-Dclearcase.disable.caches=true" JVM option to check if the caches are the cause of the problem.

And can you please provide me your TC server debug logs? I need the "teamcity-clearcase.log" and "teamcity-vcs.log" files. See http://confluence.jetbrains.net/display/TCD5/Reporting+Issues#ReportingIssues-VersionControlDebugLogging for information about enabling debug logging on your server.

Hi Maxim,
thank you for the answer. We have applied switching off the caches. And so far no problems. The difficulty is that this was not a regular bug and we could not reproduce at will so can not give a definite answer yet.
As an aside, is there documentation on caches anywhere?

Seems, there is no such documentation. So I created the task in our tracker to fix it: http://youtrack.jetbrains.net/issue/TW-12016.
