I've been provided by a web crawler but i found it to be too slow since it is single threaded. It took 30 mins to crawl 1000 webpages. I tried to create multiple threads for execution and with 20 threads simultaneously running the 1000 webpages took only 2 minutes. But now I'm encountering "Heap http://stackoverflow.com/questions/1146236/how-to-handle-out-of-memory-error-for-multiple-threads-in-a-java-web-crawler Out of Memory" errors. I'm sure what i did was wrong which was create a for loop for 20 threads. What would be the right way to multi-thread the java crawler without giving out the errors? And speaking of which, is multi-threading the solution to my problem or not? java out-of-memory share|improve this question asked Jul 18 '09 at 0:10 Tobias 4761515 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted The simple answer (see above) is to increase the JVM memory size. This will help, but it is likely that the real problem is that your web crawling algorithm is creating an in-memory data structure that grows in proportion to the number of pages you visit. If that is the case, the solution maybe to move the data in that data structure to disc; e.g. a database. The most appropriate solution to your problem depends on how your web crawler works, what it is collecting, and how many pages you need to crawl. share|improve this answer answered Jul 18 '09 at 5:04 Stephen C 390k45416741 add a comment| up vote 3 down vote My first suggestion is that you increase the heap size for the JVM: http://www.informix-zone.com/node/46 share|improve this answer answered Jul 18 '09 at 0:17 Alex Bl

Consider raising the ThreadsPerChild setting We raised our ThreadsPerChild setting from 50 to 100, but we still get the error. Our access logs indicate that these errors never even happen at periods of high load. For example, here's an excerpt from our access log (ip addresses and some urls are edited for privacy).

into a weird problem that I didn't immediately identify. Some programs just started failing: libreoffice, chrome, chromium, firefox, eclipse, ... It was quite undeterministic and depended on the system ressources being fairly well used. I thought it was a RAM issue, not having enough memory would cause programs to fail. I have somewhat agressive ram settings, but, I also have 16 GB of RAM on my computer. Well, it wasn't a memory issue, I was able to reproduce the issue with loads of memory still left over. Here's some of the messages I was getting. Libreoffice: (similar bug here) osl::Thread::create failed Java: java.lang.OutOfMemoryError: unable to create new native thread. Chrome and Chromium: pthread_create error: Resource temporarily unavailable An example of the pthread create bug on another program is here https://my.vertica.com/docs/5.0/HTML/Master/16468.htm. Some other side-effect messages appeared like: [16751:16780:0408/145921:ERROR:shared_memory_posix.cc(225)] Creating shared memory in /dev/shm/.com.google.Chrome.z77EvR failed: Too many open files [16751:16780:0408/145921:ERROR:host_shared_bitmap_manager.cc(122)] Cannot create shared memory buffer The FIX I have all kinds of browsers installed on my computer, and I'm always messing around with their configurations. I'm working on some stuff that requires using different browsers. I also have a lot of open tabs. But this bug appeared whenever I was running Chromium and Google Chrome, making me believe they couldn't be run together. The problem is that with a decent number of tabs both browser start hundreds of threads. Like 500! Here's some commands to count running threads on your system. Not sure which one is best, they give different answers: #Count all threads ps -elfT | wc -l ps -eLf | wc -l #Count threads, shows more, don't know why ps -eLo pid,cmd,nlwp | wc -l ps axms #Count threads for different browsers ps -elfT | grep firefox | wc -l ps -elfT | grep chrome | wc -l ps -elfT | grep chromium | wc -l ps -elfT | grep opera | wc -l If you do the test you'll see that chromium and chrome use huge amounts of threads. Right now I have Chrome@658 threads, Chromium@601 threads, Firefox@39 threads, Opera@4 threads. But why is there a limit an
