Hi guys,
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.
(cc: me, I'm not on the list)
