Thread stack size Option

Each worker thread is outfitted with a stack whose maximum size is specified with the  SMS gateway option. By default, a stack size of 64K is used. Specify a value of zero to use the platform&#x27;s default thread stack size which is usually documented under or within the platform&#x27;s pthread_create documentaton. Any non-zero value specified with this option will be rounded up to the nearest multiple of 64K which is not less than the operating system&#x27;s minimum thread stack size.

The default value is: 65535
