Lance, We have have thousands of searches per minute so a minute of downtime is out of the question. If for whatever reason one of our solr slaves goes down I want to remove it ASAP from the loadbalancers rotation, hence the 2 second check.
Maybe I am doing something wrong but the my HAProxy healthcheck is as follows: ... option httpchk GET /solr/items/admin/file?file=healthcheck.txt ... so basically I am requesting that file to determine if that particular slave is up or not. Is this the preferred way of doing this? I kind of like the "Enable/Disable" feature of this healthcheck file. You mentioned: "It should not run out of file descriptors from doing this. The code does a 'new File(healthcheck file name).exists()' and throws away the descriptor. This should not be a resource leak for file desciptors." yet if i run the following on the command line: # lsof -p xxxx Where xxx is the pid of the solr, I get the following output: ... java 4408 root 220r REG 8,17 56085252 817639 /var/solr/home/items/data/index/_4y.tvx java 4408 root 221r REG 8,17 10499759 817645 /var/solr/home/items/data/index/_4y.tvd java 4408 root 222r REG 8,17 296791079 817647 /var/solr/home/items/data/index/_4y.tvf java 4408 root 223r REG 8,17 7010660 817648 /var/solr/home/items/data/index/_4y.nrm java 4408 root 224r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 225r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 226r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 227r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 228r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 229r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 230r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt java 4408 root 231r REG 8,17 0 817622 /var/solr/home/items/conf/healthcheck.txt ... at it keeps going .... and I've see it as high as 3000. I've had to update my ulimit to 10000 to overcome this problem however I feel this is really just a bandaid to a deeper problem. Am I doing something wrong (Solr or HAProxy) or is this a possible resource leak?
