Dear all:
         Recently I make some change on the  kern/vfs_aio.c

     and I run proxy server "squid2-3Stable4" on the new kernel,

     But after about 20 minutes, the "squid" process is killed by the
signals

     SIGPROF, or SIGVTALRM

      I have understand SIGPROF stand for " the time of process is executing
in user and system mode"
        and SIGVTALRM is" user mode."

       But I don't can find where "squid" run too long, because squid is
killed by SIGPROF or SIGVTALRM

       Can  anyone give me a suggestion. or teach me how to know the
kernel's problem ??

       Thank you in advance .

                                                                    Sincerely
                                                                        Richard Lin
