PURGING CACHE…

[David Battistella]

What is the system config?

I find this is almost always due to not enough RAM or never shutting down the machiine.

I have a dual 2 with 3.5Gb of ram, and I get corrupted caches fairly regularly
even though the machine is shutdown every night.
Any thoughts..can you purge the cache in FCP or even from the desktop.
Thanks in advance

You can trash preferences OR you can delete the POA cache directly from the root level of the hard disk.

That might do it.

Try FCP rescue

Thanks Gary/David,
Isn’t trashing preferences alittle extreme. A shutdown is normally sufficient.
I’m just trying to avoid a fairly lengthy process to bring the machine back up.
What is the POA cache exactly and do you feel it could be a preference issue.
I’ve downloaded Rescue but not put it to use yet.
Thanks again.

prefs are only the setting for your Application, they are rebuilt to the default when the application launches.

restarting the machine will not fix a problem with a corrupt cache file, neither will restarting the app.

FCP Rescue allows you to do this and then restore a previous version of your settings. so nothing is lost.

how do you see this as extreme? more extreme than having to completely rebuild a corrupt project from scratch?

OK Gary , why don’t I have dropped frames after I have shutdown and fired up again. I do not restart, I do a proper shutdown. There must be a cache in use somewhere.

Also David mentioned the POA cache. What is it and where is it.
I’m simply curious

search for POA in spotlight ( 10.4.x)
or use the find function in the OS.

Sorry Gary, I’m not that daft, I’m in 10.3.9 and my search engine can’t find it.
What is the POA Cache anyway.

[David Battistella]

Read about how to do this as well.

THe POA cache and MOA cache are caches created by FCP. The POA can be deleted and is recreated teh next time you start FCP. Of course it will be a fresh cache once you ahve deleted and restart. Sometimes it is at the root of some FCP cache issues.
