Title: Audio Analysis 9.1.291
Post by: Phydeaux on November 04, 2003, 03:55:56 am

Hi,

I have just re-analysed my collection (about 5,000 tracks) due to the bpm changes. I have a predominantly mp3 / wma library.

I first did a batch of 100 files which was fine. Then did 2 batches of 1000 files -- both were fine. No evidence of memory leaks or crashes.

Having gained some confidence in this, I then queued all the remaining files. However, only 500 of them were processed before MC crashed without error.

This left asbout 2,100 to go which I started in a separate batch and when I woke up this morning, about 1,800 had been done (slow 800MHz pc!).

It seems much more stable, except for that one crash. If it happens in 0.2% of the time, is that acceptable?

Cheers.

P.

FWIW, I'm [finally] analyzing my collection (~8000 files) and I've found that on my system "Handles" seem to be leaking during Replay Gain Analysis.

This is on a relatively old PC (450 MHz PIII, 384MB memory).  I was using the XP "Task Manager" to keep an eye on things via the "Performance" tab.  I started out with about 4400 handles in use and after about a tenth of the files had been analyzed this was up to about 14000.

It was wierd in that the number of handles would climb up and fall back but never quite all the way back then climb a bit higher (lather, rince, repeat).

Also odd: exiting MC didn't seem to release the handles (implying MC isn't the problem?).

Version 9.1.319

Does anyone else see leaking handles? (we don't)

If so, what file types are you analyzing, and what version of MC?

Thanks.

I'm analyzing ~1000 files right now.  How do I check?

On W2K / XP:

Task Manager, then show the 'Handles' column.

You can also watch the total system handle count on the 'Performance' page.

Seems pretty stable here.  A couple hundred mp3 files down, and it hasn't moved more than 2-3 in any direction.

I have analyzed several thousands (MC10) and never found a memory leak or a crash without error.

I localized the problem.   Matt's tip to add the Handles column to the Process tab showed that it wasn't MC allocating the handles it was a program called mainserv.exe which is part of the UPS software that came from APC (http://apc.com/index.cfm?isoCountryCode=us).

Why this software cared what MC was up to I have no idea but when I upgraded the from version 1.2 to 1.4 (http://apc.com/tools/download/software_comp.cfm?sw_sku=SDW%2085) the problem went away.

I'd be curious to know if those people who once had problems with audio analysis have UPSes from APC.  It's a pretty popular brand of UPS.
