    WorkerStackSize Directive

    + + + + + + + + +
    Description:The size in bytes of the stack used by threads handling +client connections
    Syntax:WorkerStackSize size
    Default:varies by operating system
    Context:server config
    Status:MPM
    Module:leader, mpm_winnt, perchild, threadpool, worker
    Compatibility:Available in Apache 2.1 and later
    +

    The WorkerStackSize directive sets the + size of the stack (for autodata) of threads which handle client + connections and call modules to help process those connections. + In most cases the operating system default for stack size is + reasonable, but there are some conditions where it may need to be + adjusted:

      +
    • On platforms with a relatively small default thread stack size + (e.g., HP-UX), Apache may crash when using some third-party modules + which use a relatively large amount of autodata storage. Those + same modules may have worked fine on other platforms where the + default thread stack size is larger. This type of crash is + resolved by setting WorkerStackSize to a + value higher than the operating system default. This type of + adjustment is necessary only if the provider of the third-party + module specifies that it is required, or if diagnosis of an Apache + crash indicates that the thread stack size was too small.
      • + +
    • On platforms where the default thread stack size is + significantly larger than necessary for the web server + configuration, a higher number of threads per child process + will be achievable if WorkerStackSize is + set to a value lower than the operating system default. This type + of adjustment should only be made in a test environment which allows + the full set of web server processing can be exercised, as there + may be infrequent requests which require more stack to process. + A change in the web server configuration can invalidate the + current WorkerStackSize setting.
