Re: threading issue on freebsd 5.3

[Shie Erlich]

also, the "sleeping" usually show


#0  0x282bead6 in _thread_kern_sched () from /usr/lib/libc_r.so.5
#1  0x282b4948 in pthread_yield () from /usr/lib/libc_r.so.5
#2  0x0807fce2 in ost::ThreadImpl::ThreadExecHandler (th=0x81be500) at
thread.cpp:1099
#3  0x282b7009 in _thread_start () from /usr/lib/libc_r.so.5
#4  0x00000000 in ?? ()

on the gdb backtrace.

does this help?
