Renee Sun commented on SOLR-2138: --------------------------------- yes, same JVM, jre1.6.0_21. By the way, in solr_user blog, I added more information after more test... I have commented out the newSearcher and firstSearcher in solrconfig.xml, after that it loaded up all 130 cores in 1 minutes. It only took totally 1GB memory, whereas with Solr 1.3, with newSearcher and firstSearcher, it took about 1 minute and 6.5GB on same core. > Solr 1.4 takes long time to load cores (memory leak?) > ----------------------------------------------------- > > Key: SOLR-2138 > URL: https://issues.apache.org/jira/browse/SOLR-2138 > Project: Solr > Issue Type: Bug > Affects Versions: 1.4 > Environment: 8 processors Intel(R) Xeon(R) CPU E5345 @ > 2.33GHz > Reporter: Renee Sun > > 1. 32 GB total memory, with 16GB allocated to Solr server. > 2. 130 cores, with most cores having 50,000 documents, and 2,3 cores having > 1~2.4Million documents (largest core takes about 11GB disk space) > 3. in solr 1.3, there was no problem, it took 5,6 minutes to load up all > cores. > 4. just upgrade to solr 1.4, it takes about 45+ minutes to load all 130 cores. > 5. no solrconfig or schema change > 6. autowarmCount="0" for all caches > I have monitored the memory with JConsole. The 'queryConverter' warning in > catalina.out file helped me figured out that when about 70 cores were loaded, > the memory usage went from 300MB to 16GB, and stay at that level. Rest of the > cores are loaded up extremely slow. > I find Yonik's fix note for SOLR-1797: fix ConcurrentModificationException > and potential memory > leaks in ResourceLoader.
