Hi,

I've a pro*c program which uses threads. Many a times, a thread exits due
to its inability to obtain locks over a period of time.
Here is the sample of what i've written:-

Any ideas or suggestions on optimising a multithreaded pro*c program?

for(::)
{
..........
--- my program code is here ----

It recieves packets from a client and stores them in the database

Hence I need to obtain lock.
.............
for(i=0;;i++)
{
if(i>gMaxLockAtmpts)
{
logMsg("Cannot get dbmutex lock !!! Exiting thread...");
brk=1;
break;
}
if( mutex_trylock( &dbmutex[idx] ) == 0 ) break;
sched_yield();
}
if( brk ) {
sleep(3); /* invoking thread alone sleeps */
break;
}



}

close(socket)
pthread_exit((void *)0);

}
