java.lang.OutOfMemoryError: Failed to fork OS thread

Try to resolve this error by increasing the delay time in consecutive threads.

This section explains the following error:

java.lang.OutOfMemoryError: Failed to fork OS thread

This error occurs when thousands of threads are started in very quick succession (almost simultaneously). The error indicates that the upper limit on the number of concurrent threads for the JVM has been reached.

Normally this error occurs when a Javascript loop starts thousands of threads in a very short period of time. This error should not occur in normal conditions in which IBM® Security Verify Directory Integrator solutions usually operate.

You can avoid this error by inserting a very small delay between starting successive threads (even as small as 1 millisecond). This delay can cause performance to decrease a little, but the error would disappear.
