Hi All,
We have multiple indexes in our linux system each of which has a decent
size (occupying a few gigs). We are facing few issues while opening an
IndexReader for some of those indexes.
java.io.IOException: Map failed ,% STACK:
sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:758)

The system has 64GB RAM and here is o/p of ulimit -a

data seg size (kbytes, -d) unlimited

max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited

pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200

stack size (kbytes, -s) 32768
cpu time (seconds, -t) unlimited

Any help would be greatly appreciated.
