How to solve error IpcSemaphoreCreate in Cygwin

Hello All

When trying to start postmaster (7.3.1) the following error occurs:

IpcSemaphoreCreate: semget(key=5432083, num=17, 03600) failed: No space
left on device

This error does *not* mean that you have run out of disk space.

It occurs when either the system limit for the maximum number of semaphore
sets (SEMMNI), or the system wide maximum number of semaphores (SEMMNS),
would be exeeded. You need to raise the respective kernel parameter.
...

How can I change the kernel parameters in Cygwin? Or is there any other
solution to this problem?

Tanks in advance
