the "right" value is besides trial and error?Our site gets extremely minimal traffic so I'm really puzzled error opening new searcher. exceeded limit of maxwarmingsearchers why theout-of-the-box settings are insufficient.The index has about 61000 documents, very small, and we do less than onequery per second.-jsd- reply Tweet Search Discussions Search All Groups maxwarmingsearchers solr config solr-user 11 responses Oldest Nested Yonik Seeley I'd advise setting it to a very low limit (like 2) and committing less often. Once you get too many overlapping searchers, things will slow to a crawl and that will just cause more to pile up. The root cause is simply too many commits in conjunction

with warming too long. If you are using a dev version of Solr 1.4, you might try commitWithin instead of explicit commits. (see SOLR-793) Depending how long warming takes, you may want to lower autowarm counts. -Yonik Yonik Seeley at Jan 30, 2009 at 7:21 pm ⇧ I'd advise setting it to a very low limit (like 2) and committing lessoften.

simpleweb ! co ! uk [Download message RAW] Hi, Solr seems to be crashing after a JVM exception that new threads cannot be created. I \ https://marc.info/?l=solr-user&m=128031446330083 am writing in hope of advice from someone that has experienced this before. https://issues.alfresco.com/jira/browse/ACE-2319 The \ exception that is causing the problem is: Exception in thread "btpool0-5" java.lang.OutOfMemoryError: unable to create new \ native thread The memory that is allocated to Solr is 3072MB, which should be enough memory for a \ ~6GB data set. The documents are not big either, they have around 10 error opening fields of which \ only one stores large text ranging between 1k-50k. The top command at the time of the crash shows Solr using around 1500 threads, which \ I assume it is not normal. Could it be that the threads are crashing one by one and \ new ones are created to cope with the queries? In the log file, right after the the error opening new exception, there are several thousand commits \ before the server stalls completely. Normally, the log file would report 20-30 \ document existence queries per second, then 1 commit per 5-30 seconds, and some more \ infrequent faceted document searches on the data. However after the exception, there \ are only commits until the end of the log file. I am wondering if anyone has experienced this before or if it is some sort of known \ bug from Solr 1.4? Is there a way to increase the details of the exception in the \ logfile? I am attaching the output of a grep Exception command on the logfile.
