warning 0000002

Hi all. I use my IHP-100 to record dj sets for several years now. I just upgraded to the latest rockbox available on the site. I was using Version: r14500-070829
before. I recorded a 6hr session tonight and when i came back to pick up the player i saw a warning 0000002 flashing on screen.
I have never had this before. Anyone knows what the problem can be?
I read somewhere else that this indicates buffer overflow . I record to PCM wave. My last recording is from a few days ago without any problems. Just Rockbox 3.0 gives me this.
IHP-100
Latest Rockbox
PCM Wave
Line-in
30gb hd
AGC on 48db max dj set slow
1gb split
I guess i should go back to the other rockbox, but...

That's a version of Rockbox from over a year ago. Please, please do not ask for support on truly ancient versions of Rockbox. If you wish to use severely outdated versions, that's up to you, but we expect posts in this forum to be about problems with the current version.

Sorry, I misread. There's no point in reporting version numbers on versions you're not actually using, though. When you said you "just" upgraded, I assumed that meant "at the time of the typing of this post" rather than before you made the recording. Otherwise, why would you be telling me the previous version's version number?
Can you reproduce the problem in the bleeding edge version?

Ok.. thats a mistake then. I just wanted to point out what i was using before.
I will download the r19185 build and have it record at night tomorrow. Then i will report back.
Do these overflow errors cause any skips? I will listen to the recording tomorrow as well to see if all is ok.
I am just listening to one recorded wav and i notice in Sound Forge there is quite some clipping here and there. The AGC was turned on. I didn't notice clipping in previous recordings. Could this have caused the 000002's?

clipping doesn't cause the warnings, the buffering system does.
How much free space is there on the disk?
Maybe you could defrag it (or format and install rockbox again).
I have seen the warning pop up when diskspace was getting low (already even at <10GB free on a fragmented disk)
edit:
warning 2 means an overflow in the encoder buffer which is a hint that it wasn't able to flush to disk in time.

There was about 12gb free after the recording was done.
I will try a format and defrag tonight as well.
But the thing is.. i have been using the player for years with the older rockbox versions without problems. So i might go back to older rockbox or use the recording enhancement pack. I should have thought about 'don't fix it if it aint broken
'

Well, the longer you use it, the more fragmented it gets...

The earlier version has one big PCM buffer which might allow a bit slower writes as the current one (where an PCM and MP3 buffer exist). So it might work fine with the earlier version, but it might not tomorrow when fragmentation gets even worse.
But the earlier version will just abort the recording when the overflow occurs, so in stead of a glitch you miss the entire recording.
That said, it is a fine balance between watermarks that do not cause overflows on one side, and battery life (spinups) on the other.
Maybe jhMikeS can add is 0.02
