Solr :: Snapshooter Cannot allocate memory
Hello
We are facing this recurrent error on our Master Solr Server
every now and then :
SEVERE: java.io.IOException: Cannot run program
"/opt/solr/bin/snapshooter" (in directory "solr/bin"):

We have 3 Solr Servers, one Master and 2 Slaves, there is a Cron
Job doing Commits every 5 minutes on Master with Inserts/Deletes and
Slaves Rsync last Index Version from Master every 10 minutes, all 3
Servers have this Setup :
* RHEL 5.0 OS 64 bits
* 16 GB RAM Memory
We are giving Solr Java process 10 GB RAM Memory, did anybody
face this error ? Snapshooter process will try to allocate memory from
the 6GB RAM Memory available for the OS ? should we reduce 10GB to 8GB
for Solr Java process ?
Thanks for your help
Pablo
Re: Solr :: Snapshooter Cannot allocate memory
Posted by Yonik Seeley <yo...@apache.org>.
The OS is checking that there is enough memory... add swap space:
