Hello,
I'm dealing with possible resource leak in cygwin on Windows-7. I'm
running a script which repeatedly calls another script (every 5
seconds). After a while script ends with memory error. All my memory
seems to be eaten by Page Table entries and in the memory map I see a
lot of cygwin processes with 4 pages allocated (I can provide screenshot
if neccessary). Is this known issue?
Attached is cygcheck output without any modification.

without the scripts or a simplified version that exhibits the issue,
it is impossible to state if it is due to any cygwin programs or it is
due to https://cygwin.com/acronyms/#PEBCAK
Hello,
I can understand this. And it might definitely be PEBKAC. But what I see
is real and I do not thing I've screwed my scripts so much.
Attached is simple reproducer I was able to get from my scripts. If you
will test it you will have to change base url in fetchData.sh.
When I run this script for a while I see a lot of 'zombie' bash, sleep
and wget processes in RamMap (they do not show in task manager). I can
provide screenshot.
If that would matter I run this scrips from truecrypted disk.

By the way, script in which language ?
Regards
Marco
