Were there any error messages just before it crashed? There were no messages. The section showing voice count per stream was all that showed up in the terminal. Ok, I was able to reproduce this bug with a couple of engine channels and a layered sound. I'm on it... Fixed with latest CVS. This issue is verified as fixed on my end. (Closing this one does make others more apparent.) Thanks! Sure you're right. |
Hi. I'm pushing the new CVS version hard (as usual) and it's still crashing. The crash is repeatable. All voice count values are default. What I noticed was that CPU got to 100% a couple of times just before the crash. It appears that the strings group (Engine 0) used up 128 voices, or something very close to that, right around crash time. It had seen a high of 105 voices sometime around 1 minute earlier: Engine 0) Voices: 096 (Max: 105) Streams: 084 (Max: 105) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 006 (Max: 018) Streams: 006 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Engine 0) Voices: 000 (Max: 117) Streams: 000 (Max: 117) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 005 (Max: 018) Streams: 005 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Engine 0) Voices: 088 (Max: 117) Streams: 087 (Max: 117) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 008 (Max: 018) Streams: 009 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Engine 0) Voices: 009 (Max: 117) Streams: 009 (Max: 117) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 005 (Max: 018) Streams: 005 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Engine 0) Voices: 110 (Max: 117) Streams: 117 (Max: 117) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 007 (Max: 018) Streams: 007 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Engine 0) Voices: 110 (Max: 125) Streams: 114 (Max: 125) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 007 (Max: 018) Streams: 007 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Engine 0) Voices: 096 (Max: 126) Streams: 096 (Max: 125) Engine 1) Voices: 000 (Max: 016) Streams: 000 (Max: 016) Engine 2) Voices: 007 (Max: 018) Streams: 007 (Max: 016) Engine 3) Voices: 000 (Max: 052) Streams: 000 (Max: 052) Here's what I could get from a backtrace: 0xffffe410 in ??
