Increasing the stack size on Windows, Linux, and UNIX systems

Increase the stack size on Windows, Linux, and UNIX systems by setting the MQSI_THREAD_STACK_SIZE environment variable to an appropriate value.

When you restart brokers that are running on the system, they use the new value.

The value, in bytes, of MQSI_THREAD_STACK_SIZE that you set is used for every thread that is created in a DataFlowEngine process. If the integration server has many message flows assigned to it, and you set a large value for MQSI_THREAD_STACK_SIZE, the DataFlowEngine process needs a large amount of storage for the stacks.

Set this environment variable to at least 48 KB. The default values are:
Linux and UNIX
1 MB
AIX®
2 MB
z/OS®
50 KB
Windows
Determined by the operating system.
