zhuojunjian created SOLR-4698:
---------------------------------
Summary: "java.lang.OutOfMemoryError: Map failed" when run in
JRE64
Key: SOLR-4698
URL: https://issues.apache.org/jira/browse/SOLR-4698
Project: Solr
Issue Type: Bug
Components: scripts and tools
Affects Versions: 4.0
Environment: CPU:4 cores
Memory:64G
Hard Disk:2.5T
OS:linux
Reporter: zhuojunjian
Fix For: 4.3
we make solr run in tomcat. and now there are 10 million records desployed
averagely in solrcloud which has 3 shards. each record's size is about 1.5k.
first we used JRE32. then we found it was not fast enough when the current
search request count reached 300.
so we think maybe the memory assigned for solr is not enough. and we replace
JRE32 with JRE64, and set "JAVA_OPTS="-Xms2048m -Xmx5120m"" in
$TOMCAT_HOME/bin/catalina.sh. but when we restart the solrcloud, we find it
failed. the error log is below:
