Subject: Maximum packet size exceeded in a request

Does anybody know in what situation "Maximum packet size exceeded in a
request" from _sess_read() in snmp_api.c could happen? Is following
related?

Here is what I found,=20

msgMaxSize is set different between udp and tcp. Is it supposed to be
the same?

For tcp (in both snmplib/snmpTCPDomain.c and snmplib/snmpTCPDomain.c),
it sets
t->msgMaxSize =3D 0x7fffffff;

For udp (snmplib/snmpUDPDomain.c)
t->msgMaxSize =3D 0xffff - 8 - 20;
For udp (snmplib/snmpUDPIPv6Domain.c)
t->msgMaxSize =3D 0xffff - 8 - 40;

For unix (snmplib/snmpUnixDomain.c)
t->msgMaxSize =3D 0x7fffffff;


Thanks,

FT
