I am still playing around with load/stress testing my FDS install. I
am using slamd to run the tests, and I am running the basic load, and the basic search
tests against my test boxes, The slamd client and the FDS server are on identical
hardware running RHEL4 with 2G memory, and 2 Intel Xeon 3.6GHz processors. The issue I am
seeing is that I am getting "cannot connect to the ldap server" errors once I
push the "threads per client" past 2400. My question is am I hitting a limit on
the OS (max tcp connections)? Or a FDS limit? My assumption was that given appropriate
hardware, and proper configuration, I could expect FDS to handle more than 2400 concurrent
connections. Any insights as to what I might be missing would be greatly appreciated.
Log entries from your server should give you some insight into why
connections are being refused.
There's a good chance you haven't allocated enough file handles, but
that's a guess.
