Hi
Apologies for the Long wait.......... My Linux system on ulimit -a respresent core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 1983 virtual memory (kbytes, -v) unlimited The Problem of "Too many Open Files" happens on every 2nd Search being done I think as u say "open files (-n) 1024" should be increased........... More Advises is Accepted greatefully....

All pre-existing indexes will still be in the multi-file format. - number of documents does not directly impact the number of files needed by Lucene. If the index is really in a compound file format (see above), and is optimized, you will need a fixed number of file handles. Even if the index is in a multi-file format, the number of files needed depends on the number of indexed *fields* in the index (not documents). - do you get the error on the first and every search or only once in a while? Perhaps where there are lots of concurrent users? Perhaps after you've done X searchers? - check your OS-level setting for the number of open files. This is shell/system-dependent somewhat, but "ulimit -a" should get you started. The number of open files should be large enough to allow for all files and sockets that your application needs to open. In a typical server-side Java app setting this value should be around 8000. Defaults are much smaller, so unless you have changed this, this may be the answer. - look into "lsof" utility. It can display all file handles in use by a given process. This is a good tool to troubleshoot "too many open files" issues. Good luck.
