What’s New in iPlanet Web Server, Version 4.1

WaitingThreads 47

BusyThreads 1

Thread limits 48/512

Total Sessions 48/712

The ActiveThreads, WaitingThreads, BusyThreads, and Thread limits entries have not

changed.

The

Total Sessions entry used to be Total Sessions Created. The maximum value is now

much lower (

RqThrottle + KAPool). The way iPlanet Web Server, Enterprise Edition version 4.1

frees threads has been streamlined to improve server performance, especially on heavily loaded

sites (>12K hits per minute).

When the server hits its

RqThrottle + KAPool limits (712 in this case), an error is entered into the

errors log as follows:

[date][pid] The server has created it configured maximum number of threads, %d.

This error is generated once in the lifetime of a process, and is generated for each child process if

MaxProcs is greater than 1.

Reaching the maximum number of configured threads is not necessarily undesirable, and you need

not automatically increase the number of threads in the server. More does not always mean better.

Reaching this limit only means that the server needed this many threads at some moment (at peak

load), but as long as it was able to serve requests in a timely manner, the server is adequately tuned.

If you check your

perfdump output on a regular basis and notice that BusyThreads is often near the

RqThrottle maximum, you should consider increasing your thread limits.
