It won't open the connection once the listen queue has filled up (if it did then all that would happen is the box would run out of kernel memory). The problem is likely that the thread which calls accept() is not processing the new connections as fast as they arrive. Once that state is achieved, the queues fill and SYNs will be dropped. -- 389 users mailing list 389-us...@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/389-users

The server probably still processes new connections in a single thread (it did on Unix platforms last time I looked at the code at any rate). So although the CPU load overall is not 100%, once you max out one core, it won't be able to process new connections any faster. That said, the rate you are achieving seems quite low for a modern machine. It would be worthwhile looking to see if it is doing a reverse DNS lookup on the client IP address. After that, try using pstack to see what the accept thread is spending its time on. -- 389 users mailing list 389-us...@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/389-users

Yes. Import an almost empty LDIF file. You can also copy the on-disk database underneath a server (when it is shut down), if you know what you're doing. -- 389 users mailing list 389-us...@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/389-users
