IceUtil::Thread::run(): terminate called recursively Cond.cpp

[spsoni]

Hi,

I am using Ice 3.2.1 on FreeBSD.

I am getting following error:

IceUtil::Thread::run(): uncaught exception: terminate called recursively Cond.cpp

Backtrace is as follows:

I am running few test cases on individual components of my application. Therefore, in above component, there is no Ice messaging except Monitor and Threads from IceUtil.

The above exception is occuring when I slow down my application by printing high frequency of debug information ( cout<<" SOme debug ..."<<flush; ).

Code snippet as follows:

	for(int i=1;i<=100000;i++) {
		while(true) {
                        //Job is sub-class of IceUtil::Monitor<IceUtil::Mutex>
			Job *data = new Job("xxx", DB_PUT);   //proxy_put_adapter.cpp:28
			try {
                                //Following put operation is where I print some debug information.
                                //If I reduce the debug info frequency, exception does not occur at line 28, above.
				smart_queue_->put(data, DB_PUT);
				break;
			} catch(...) {
				continue;
			}
		}
	}

I hope, my problem is clear from this post. I can provide you will full component code, if required.

I am not sure, but I suspect, my problem could be somewhat related to reasons similar to this post.


Thanks.

Hi,

You should catch the exception and print it out so that we can figure out why the condition variable of the IceUtil::Monitor can't be created:

try
{
    Job *data = new Job("xxx", DB_PUT);
}
catch(const IceUtil::Exception& ex)
{
    cerr << ex << endl;
    throw;
}

Is the Job object correctly released? If not, it's likely that your process is running out of system resources.

Cheers,
Benoit.

Thanks Benoit.

Yes, its certainly a system getting out of resource problem.

Garbage collection fixed the problem.

Apologise for posting message before proper investigation.

Cheers.
