encountered the "Cannot allocate memory" when calling snapshooter program after optimize command

[Justin Yao <ju...@snooth.com>]

Hi,

I configured solr to listen on postOptimize event and call the 
snapshooter program after an optimize command. It works well when the 
Java heap size is set to less than 4G. But if I increased the java heap 
size to 5G, the snapshooter program can't be successfully called after 
the optimize command and error message is here:

SEVERE: java.io.IOException: Cannot run program 
"/home/solr_1.3/solr/bin/snapshooter" (in directory 
"/home/solr_1.3/solr/bin"): java.io.IOException: error=12, Cannot 
allocate memory
         at java.lang.ProcessBuilder.start(ProcessBuilder.java:459)
         at java.lang.Runtime.exec(Runtime.java:593)

Here is my server platform:

OS: CentOS 5.2 x86_64
Memory: 8G
Solr: 1.3


Any suggestion is appreciated.

Thanks,
Justin

Justin,

Please check solr-user archive on markmail.org and search for "overcommit" or even "Whitman" to find a recent thread that I believe has the answer to this question.
