If this helps figure out the problem, I've added the following code to
db.c, ast_db_put() and this appears to have alleviated the lockup
{
int attempts = 10;
while (ast_mutex_trylock(&dblock) != 0) {
// didn't lock
attempts--;
usleep(100);
if (attempts <= 0) {
ast_log(LOG_ERROR, "ast_db_put() COULD
NOT LOCK. Abandon.\n");
return -1;
}
}
}
Now my logs are filling up with could not lock, but at least I'm not
locking up entirely anymore.
