Thanks Suresh.
I ran strace and for some reason, it cleaned out the queue...
I'm not exactly sure why snmpd gets stuck. When I keep strace open and I
send a snmpwalk to the host and it starts to hang again. I see alot of
functions being called, but the only somewhat error-like notification I
can find is this one:
open("/etc/hosts.allow", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/etc/hosts.deny", O_RDONLY) = -1 ENOENT (No such file or
directory)
Which is correct, cause they don't exist. Could snmpd really crash
because of this???
