We have a customer running net-snmp-5.7.1 on Solaris 10/x86 and
they're seeing some type looping wrt an NFS filesystem whose size >
2TB:
statvfs("/var/run", 0x08046E70) = 0
ioctl(13, MNTIOC_GETMNTENT, 0x08046A08) = 0
statvfs("/export", 0x08046E70) = 0

statvfs("/export/home", 0x08046E70) = 0
ioctl(13, MNTIOC_GETMNTENT, 0x08046A08) = 0
statvfs("/rpool", 0x08046E70) = 0
ioctl(13, MNTIOC_GETMNTENT, 0x08046A08) = 0

Apparently, the the EFBIG and EOVERFLOW is because of filesystems
which are larger than 2TB. I tried building 5.7.1 on this platform
with LFS and run into the following:
/opt/fsw/bash42/bin/bash ../../libtool --mode=compile cc -I../../include -I.
-I../../agent -I../../agent/mibgroup -I../../snmplib
-I/opt/TWWfsw/libopenssl10/include -mr -Qn -xstrconst -xO2 -xtarget=pentium4
-Dsolaris2=solaris2 -c -o hardware/memory/memory_solaris.lo
hardware/memory/memory_solaris.c
cc -I../../include -I. -I../../agent -I../../agent/mibgroup -I../../snmplib
-I/opt/TWWfsw/libopenssl10/include -mr -Qn -xstrconst -xO2 -xtarget=pentium4
-Dsolaris2=solaris2 -c hardware/memory/memory_solaris.c -KPIC -DPIC -o
hardware/memory/.libs/memory_solaris.o
"/usr/include/sys/swap.h", line 49: #error: "Cannot use swapctl in the large
files compilation environment"
cc: acomp failed for hardware/memory/memory_solaris.c
gmake[2]: *** [hardware/memory/memory_solaris.lo] Error 1
gmake[2]: Leaving directory `/opt/build/net-snmp-5.7.1/agent/mibgroup'
So, we might need to make the necessary code aware of the 64-bit
statvfs() functions to resolve this problem unless there is a solution
to the above which I cannot see.
