Re: CreateFileMapping Problem


hi,

yesterday we upgraded the cygwin.dll to version 1.5.21-2 (just the dll, 
that why cygcheck still reports 1.5.20-1). our nighty build (takes a few 
hours) ran successfully. but this morning, as multiple users were logged 
in, we got the same CreateFileMapping error again.

as a workaround we removed the "Global\" prefix from the mapping objects 
and it seems to work fine this far. of course, this is no real fix, but 
since the server has enough resources and our make process wont error out 
its okay i assume.

first noticable difference is that the root user cant see other users 
processes.

the server is a dual-cpu dual-core opteron 280 2.4ghz with 8gb of ram. i 
noticed that top and /proc/meminfo only show 4gb of total ram with 0k 
used. if less then 4gb are free those values are changing.

here's the cygwin -s output:
