bbsiz

Maximum memory per process.

Synopsis

[config]    bbsiz=n

Description

The value n is the maximum memory allocation permitted for a process (in kilobytes). This amount of process private memory is used for symbol table allocation and various other memory requirements, including I/O devices. It is allocated in increasing extents as required by the application until the maximum is reached. When a process starts, its initial allocation is 128 kilobytes.

Once this memory is allocated to the process, it is generally not deallocated until the process exits. However, when a large amount of memory is used (for example greater than 32MB) and then freed, Cache attempts to release deallocated memory back to the operating system where possible.
