Hello All,
I've been a happy Cygwin user for a years now with no issue. Recently
(last few months) I've started having many problems with a variety of
apps. Because of the number of apps with which I have an issue I
suspect it might be an issue with the cygwin DLL and memory allocation
after forking.

I've spent a fair amount of time Googling for a solution and although
I've found a number of people with a similar issue I've not found
anything yet.
So my questions:
- Is this the right group to ask this in?
- Is this a known issue?
- Is it my environment? I've tried a complete re-install with no
change. I've tried recent CVS builds of the cygwin DLL with no luck.
- Is it related to my system? (Thinkpad T43 with 2GB RAM, Windows XP Pro SP2).
- I've also tried adding the reg key heap_chunk_in_mb
(HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin) (as a DWORD).
I've
tried setting this to 256, 512 and 768 MB. No success here either.
- No amount of 'rebase'-ing seems to have helped either.
Any pointers, comments or suggestion would be really, really appreciated.
I'm really hoping to find a solution to this...
Many thanks in advance
SM
