I know that mail isn't the best method perhaps, but before I open a PR, I thought I'd try again... My last recent update revealed a bug perhaps. I'm now running: FreeBSD dakota 5.4-PRERELEASE FreeBSD 5.4-PRERELEASE #28: Wed Mar 23 20:38:58 CET 2005 root@dakota:/usr/obj/usr/src/sys/DAKOTA64 amd64 The system seems to have problems with filedescriptors. It's not otherwise loaded and it's happed enough that I thought I should mention it before 5.4 goes out the door (around 50% of the time). How to repeat: mpg123 -b 1024 --list playlist (where playlist is a simple list of .mp3 files) I get this error message: Could not resync/reset buffers: Interrupted system call and the program simply hangs using 90%+ cpu I've ktraced the hanging binary, but the result is sort of monotonous. The ktrace.out file is filled with this simple set of lines: 94680 mpg123 RET read 0 94680 mpg123 CALL select(0x400,0x7fffffffe310,0,0,0) 94680 mpg123 RET select 1 94680 mpg123 CALL read(0x5,0x7fffffffe2ff,0x1) 94680 mpg123 GIO fd 5 read 0 bytes "" I haven't done the legwork yet to track this down to a closer time period than sometime since my last kernel&world, 25 december 04.
