    <p>I'm developping an application in C in a Linux environment. I've noticed that the following code leaks tons of memory after only hundreds executions :</p> <pre><code>do { pthread_t flushThread; pthread_attr_t attr; logevent_thread_t logThread = { Db , &amp;do_curl }; if (( pthread_attr_init ( &amp;attr ) == 0 ) &amp;&amp; ( pthread_attr_setdetachstate ( &amp;attr , PTHREAD_CREATE_DETACHED ) == 0 ) ) { pthread_create ( &amp;flushThread , &amp;attr , (void*)FlushThread , (void*)&amp;logThread ); pthread_attr_destroy ( &amp;attr ); } } while(1); </code></pre> <p>When I started with the code, I only used pthread_create(), but when I noticed the leak, I started google'd and searched StackOverflow, and found the following URLs :</p> <ul> <li><a href="https://stackoverflow.com/questions/3098655/pthread-create-memory-leak">pthread_create memory leak</a></li> <li><a href="https://stackoverflow.com/questions/5610677/valgrind-memory-leak-errors-when-using-pthread-create">valgrind memory leak errors when using pthread_create</a></li> </ul> <p>That's why I initialize the attributes and start the thread "detached". I also destroy the attributes. I can not use pthread_join() since I don't want a blocking call, I want my thread to live on his own.</p> <p>Unfortunately, the leak is still there. I've no more ideas, and will get any further advice !</p> <p>Thank you !</p> <hr> <p>@arrowdodger: Calling pthread_detach() without setting any kind of attributes also leaks. I also tried with setdetach and pthread_detach() without success.</p> <p>@drhirsch : I know it leaks because when I have it run for 1 day, I get a "Out Of Memory" kernel panic. Additionnaly, using top I can see more and more memoery dedicated to my process (but I understand the best way to minitor this is to use valgrind).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
