Does the snmpd daemon has a size limit for setting strings?

Is there a chance that snmpd trunctuates a string that is larger than 910 chars? I try to run this from a client: snmpset -v3 -u user 1.1.1.17 .1.3.6.1.4.1.50000.1.10 string "/tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. = \\\"0xff000000\\\")] | /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. = \\\"0xff000000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. = \\\"0xffffff00\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. != \\\"0xffff0000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. = \\\"0xffff0000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. != \\\"0xffff0000\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. < \\\"0\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. > \\\"0\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l2_from_site\\\") and (. != \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l2_from_site\\\") and (. > \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l3_dest_site\\\") and (. < \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l3_dest_site\\\") and (. \\\"0\\\")] | /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. = \\\"0xff000000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. = \\\"0xffffff00\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. != \\\"0xffff0000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. = \\\"0xffff0000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. != \\\"0xffff0000\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. < \\\"0\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. > \\\"0\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l2_from_site\\\") and (. != \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l2_from_site\\\") and (. > \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l3_dest_site\\\") and (. < \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l3_dest_site\\\") and (. \\\"0\\\")] | /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. = \\\"0xff000000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. = \\\"0xffffff00\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.src\\\") and (. != \\\"0xffff0000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. = \\\"0xffff0000\\\")] & /tigerXML/ip/field[(attribute::name = \\\"ip.dst\\\") and (. != \\\"0xffff0000\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. < \\\"0\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. > \\\"0\\\")] & /tigerXML/tcp/field[(attribute::name = \\\"tcp.dstport\\\") and (. \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l2_from_site\\\") and (. != \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l2_from_site\\\") and (. > \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l3_dest_site\\\") and (. < \\\"0\\\")] & /tigerXML/prot/field[(attribute::name = \\\"prot.l3_dest_site\\\") and (. \\\"0\\\")]" And in the server I have this line in snmpd.conf: "pass .1.3.6.1.4.1.50000.1 /opt/tiger/scripts/handler.sh" handler.sh is just a python script that dumps all arguments vector into a file, this is the output: I was called with ['/opt/tiger/scripts/handler.sh', '-g', '.1.3.6.1.4.1.50000.1.10'] I was called with ['/opt/tiger/scripts/handler.sh', '-s', '.1.3.6.1.4.1.50000.1.10', 'string', '/tigerXML/ip/field[(attribute::name = "ip.dst") and (. = "0xff000000")] | /tigerXML/ip/field[(attribute::name = "ip.src") and (. = "0xff000000")] & /tigerXML/ip/field[(attribute::name = "ip.src") and (. = "0xffffff00")] & /tigerXML/ip/field[(attribute::name = "ip.src") and (. != "0xffff0000")] & /tigerXML/ip/field[(attribute::name = "ip.dst") and (. = "0xffff0000")] & /tigerXML/ip/field[(attribute::name = "ip.dst") and (. != "0xffff0000")] & /tigerXML/tcp/field[(attribute::name = "tcp.dstport") and (. < "0")] & /tigerXML/tcp/field[(attribute::name = "tcp.dstport") and (. > "0")] & /tigerXML/tcp/field[(attribute::name = "tcp.dstport") and (.

Am I doing something wrong or this is a known limit? Can I somehow increase this limit?
