When a Passive-mode transfer is requested, TIdFTPServer is going to try opening each port in the range until it finds one that is available.Īs for NoReservedRangePort, if it is enabled then TIdFTPServer will reject an Active-mode transfer that requests a connection to a port between 1-1024, inclusive. And it is to close tcp by sending RST instead of four waves to. Whether or not the PASV range of ports is too large depends on how many simultaneous transfers you want to support, and how many other socket apps are running along your server. The socket tcp connection will be closed when the java program exits and the process is killed. I already checked that the arguments for the bind. I having a strange problem where the first run of the application always fails on the bind of the first socket with Cannot assign requested address but the second time i run the application everything works as expected. These are inbound connections, so multiple transfers can be bound to the same port at the same time if different IP/Port sources are connecting. I am developing an application that uses datagram sockets for communication. Passive-mode transfers, which are bound to DefaultDataPort when PASVBoundPortMin/Max are 0.These are outbound connections, so multiple transfers can be bound to the same port at the same time as long they are connecting to different IP/Port targets. Threats include any threat of suicide, violence, or harm to another. all Active-mode transfers, which are bound to DefaultDataPort. Harassment is any behavior intended to disturb or upset a person or group of people.And the only times that TIdFTPServer binds a socket to a specific port are:
The specific error message you have shown is only raised under one condition - failure to bind a socket to a specific port, not to a range of ports. MessagingException: Could not convert socket to TLS nested exception is. But where is port 40913 coming from? For that matter, where is your error message actually coming from and what does the call stack look like when the error is raised? Indy does not add IP/Port information to that error message, so were are you getting it from? So this morning after a reboot, I started getting the following error.

60963 is in your PASV port range, but TIdFTPServer would not raise a bind error on a Passive-mode transfer unless the full range of PASV ports is exhausted (and even then, the error message would be different). Things to look at:ġ) ease of use in your environment (in the case of NetBeans it is likely that the built in profiler is easiest.What you describe does not make sense. The answer is highly subjective and totally depends on your needs.

The code I profile isnt HUGE so I cannot say if the time spent in profiling is a major factor. Netbeans does the job well enough (it was a bit rough when it first came out… but much better now). I have used paid profilers as well as the Netbeans one. MPI binding for Java, there have been many projects which. If you are using Netbeans already then starting up the profiler is easy (unless you are using a Maven based project… sigh). MPI for Java is normally known as Message Passing in Java (MPJ).
Jprofiler error could not bind socket free#
What advantages have a commercial Java profiler over the free ones, e.g. For example, in JProbe you can view heap shapshots visually as a graph, select nodes to investigate and then delete references to see if the instance could then be garbage collected. JProbe has superior tools for comparing heap snapshots and finding the root cause of a memory leak. For performance profiling I have found Netbeans quite useful but where JProbe is superior is for memory profiling. Searching the web i got some very old entries about a conflict with named, which i do not have installed. I have experience using both NetBeans profiler and JProbe. I've edited /etc/nf to include the 127.0.0.1 address as the first name server, and created the pdnsd user as instructed by the wiki page.
Its not expensive compared to the cost of a developers time. However, for paid work theres no reason not to buy a better tool.
Unlike IntelliJ, I wouldnt buy a JProfiler licence for my personal projects because, unlike an IDE, its not a tool you use all day every day. I have to use NetBeans to use the NetBeans profiler, which is an inconvenience because I have to manually configure a free-form project to match the layout of my project. Its easier to get started, easier to interpret the information and, although I havent measured it, it seems that JProfiler has less of a negative impact on the performance of the application being profiled.Īlso, JProfiler integrates nicely with IntelliJ IDEA. In my experience with JProfiler, its just an all-round slicker experience than the NetBeans profiler.
