Here is a back trace of the hanged process:
(gdb) bt
#0  0x00002aaaab31c86a in pthread_cond_wait@@GLIBC_2.3.2 () from
/lib64/tls/libpthread.so.0

#4  0x0000000000404cad in main (argc=4, argv=<value optimized out>) at
dtest.c:375

please note that my version of dtest has some small changed, but line
894 is the following code:

        ret = dat_evd_wait( h_conn_evd, DAT_TIMEOUT_INFINITE, 1, &event,
&nmore );
        if(ret != DAT_SUCCESS) {
                fprintf(stderr, "%d Error dat_evd_wait: %s\n",
                                getpid(),DT_RetToString(ret));
        }
        else {
                LOGPRINTF("%d dat_evd_wait for h_conn_evd completed\n",
getpid());
        }
