- Subject: CreateFileMapping Problem
hi,
we have cygwin installed on a development windows server. os is windows
server 2003 standard r2 x64, and users are logging in through opensshd and
rdesktop. we're encountering this problem:
2 [main] bash (4544) C:\cygwin\bin\bash.exe: *** fatal error -
C:\cygwin\bin\bash.exe: *** CreateFileMapping
Global\cygwin1S4.cygpid.4544, Win32 error 0. Terminating.
it happens to all users to all kind of cygwin-processes (make, bash, sed,
...) at (as it seems) random times. it only happens to global mappings
with error always set to zero and it seems to occur more often on more
concurrent (multiuser) make instances. our make process spawns alot of
additional processes. it doesnt matter if the user is logged in through
sshd (openssh installed as a cygwin service) or rdesktop.
while digging through the mailinglist, i found two possible solutions:
1) rebase the whole cygwin installation
2) give the sshd/user more privileges (SeCreateGlobalPrivilege...)
none of the above solved our problem. today 2 users got the exact same
error message including the pid field. is there a possible conflict and
users connected through terminal services can have identical
(cygwin/windows) pids?
code in question is:
cygwin/src/winsup/cygwin/cygheap.cc
cygheap_init ()
cygwin/src/winsup/cygwin/pthread.cc
mangle_sem_name ()
cygwin/src/winsup/cygwin/shared.cc
open_shared ()
shared_name ()
any feedback is appreciated as this problem breaks our build process.
thx in advance,
andre
