Hello,
i've just installed FreeBSD 4.1-RELEASE on an Intel-Pentium-II Server and am running into problems with top:
When I start top, the process seems to hang before it can display anything! Even "truss top" showed the same behaviour.
Attaching truss to a "hanging" top process works. Top seems to hang in some kind of endless loop:
recvfrom(0x4,0x80d9060,0x900,0x0,0xbfbfef54,0xbfbfeed0) = 116 (0x74)
gettimeofday(0xbfbfef8c,0x0) = 0 (0x0)
getpid() = 209 (0xd1)
getsockname(0x4,0xbfbfebd8,0xbfbfebb8) = 0 (0x0)
gettimeofday(0xbfbfef8c,0x0) = 0 (0x0)
getpid() = 209 (0xd1)
getsockname(0x4,0xbfbfebd8,0xbfbfebb8) = 0 (0x0)
sendto(0x4,0x80d9960,0x54,0x0,0x80d9008,0x10) = 84 (0x54)
gettimeofday(0xbfbfeef4,0x0) = 0 (0x0)
select(0x5,0xbfbfef64,0x0,0x0,0xbfbfeeec) = 1 (0x1)
recvfrom(0x4,0x80d9060,0x900,0x0,0xbfbfef54,0xbfbfeed0) = 116 (0x74)
gettimeofday(0xbfbfef8c,0x0) = 0 (0x0)
getpid() = 209 (0xd1)
getsockname(0x4,0xbfbfebd8,0xbfbfebb8) = 0 (0x0)
gettimeofday(0xbfbfef8c,0x0) = 0 (0x0)
getpid() = 209 (0xd1)
getsockname(0x4,0xbfbfebd8,0xbfbfebb8) = 0 (0x0)

recvfrom(0x4,0x80d9060,0x900,0x0,0xbfbfef54,0xbfbfeed0) = 116 (0x74)

getsockname(0x4,0xbfbfebd8,0xbfbfebb8) = 0 (0x0)
sendto(0x4,0x80d9960,0x54,0x0,0x80d9008,0x10) = 84 (0x54)
gettimeofday(0xbfbfeef4,0x0) = 0 (0x0)

recvfrom(0x4,0x80d9060,0x900,0x0,0xbfbfef54,0xbfbfeed0) = 116 (0x74)
gettimeofday(0xbfbfef8c,0x0) = 0 (0x0)
getpid() = 209 (0xd1)
getsockname(0x4,0xbfbfebd8,0xbfbfebb8) = 0 (0x0)
gettimeofday(0xbfbfef8c,0x0) = 0 (0x0)
... and so on ... (pid 209 was the "top" process)
I've also tried to upgrade to 4.1-STABLE (as of Aug. 9th), but there was no improvement for my problem.
The permissions of /usr/bin/top, /dev/mem and /dev/kmem seem to be ok.
Also, the ps or vmstat commands work fine on this machine.
My dmesg output, if needed (STABLE as of Aug. 9th):
