Just launch the following test loop having a look at Windows Task Manager, Page File Usage tab : while [ 1 ] do test=$(echo test) done Memory usage is constantly growing. Once Cygwin closed, memory is still used, not released. Testing with the following loop does not give the issue : while [ 1 ] do test=test echo $test done This is why I think it is a memory leak in childs (subprocesses). This problem makes the computer to get completely frozen, then a reboot seems to be the only solution. Quite problematic with daily elaborate scripts on production servers ! Could you please have a look ? Thank you very much !
