that explaing why you get 1GB FSIZE limit. RLIM_INFINITY is defined as 0x7fffffff
. Shifting it one bit to the right produces what we get when issuing kernel syscall2. So everything looks OK. See newer version http://www.uclibc.org/cgi-bin/viewcv...21&view=markup
I suggest to fix amule code to mask SIGXFSZ signal or undefine calls to resource limits.
