Hi,

Tests of this type are a normal part of “catime” (the ca performance test and “acctst” (the ca regression test). For example the following code is in catime.

 

So I am not sure what is different with your situation. Do you see this problem only when access security files are not installed? I am at the moment testing with the example server. I will need to need to run the tests again against an ordinary IOC also.

 

/*

 * test_search ()

 */

LOCAL void test_search (

ti      *pItems,

unsigned    iterations,

unsigned    *pInlineIter

)

{

    unsigned i;

    int status;

 

    for ( i = 0u; i < iterations; i++ ) {

        status = ca_search ( pItems[i].name, &pItems[i].chix );

        SEVCHK (status, NULL);

    }

    status = ca_pend_io ( 0.0 );

        SEVCHK ( status, NULL );

 

    *pInlineIter = 1;

}



I run test on Mac OS X (Intel) which also supports IPv6. When I connect to a PV (using auto_addr) I always got a warning about duplicate PV. I guess this can cause problems (see stack traces of all threads when lock occurred).

      for (p = 0; p < 1000; p++) {
        ca_create_channel (pvs[n].name,
                           pCB,
                           &pvs[n],
                           0,
                           &pvs[n].chid);
        /*epicsThreadSleep(0.1);*/
        }
