System: NetBSD test-s0 5.1.2 NetBSD 5.1.2 (NSW-WS) #3: Fri Dec 21 15:15:43 CET

For "security reasons", vsftpd tries to avoid to use a large amount of
For that reason it sets RLIMIT_AS to a fixed value defined in defs.h,
if such a limit
is present on the system.
The hardcoded value is 100MB. On 6.1 the process is about 150MB after
required libraries (without SSL-libs).
So the hard coded value is to small ...
Try to run vsftpd on NetBSD 6.1. After a connection is recieved, the
mmap() for reading
in the user config file will fail and the connection is closed again
The following patch will increase the memory limit from 100MB to 300MB.
Of couse a configurable value from the makefile would be better, but
this works (for now).
