When opening a log file, the failure reason was not checked.
Instead it was assumed to be

The UDP based Network Interface included in this

according to the snmp_net_if_recbuf sys config option.
If this option is not present, the default value is used

Snmp manager 'get-bulk-request' failure.
This is actually a UDP problem (OTP-3807). In R7 the default
receive buffer, recbuf, size of a UDP socket has incorrectly
been changed to 1024 bytes. The problem is that when a message bigger
then the recbuf size is received it is cut and sizeof(recbuf) bytes is
delivered (this is not the correct behaviour).
The simple snmp manager app included in this application did not
explicitly set the size of recbuf.
So, in R7 a get-bulk-request could easily exceed 1024
bytes, resulting in an erroneous message.
The size of recbuf for the snmp manager app is now configurable
({recbuf,integer()}
).
Note that the maximum size of outgoing/incoming message should be
set to a value less then or equal to the recbuf size!
See for example snmpEngineMaxMessageSize in
SNMP_FRAMEWORK_MIB.
Note that this problem exists in R7 only!
