The SNMP event adapter is not generating any events and mcxa trace shows the following:

'Convert::ASN1 error: decode error 30<=>04 at /opt/bmc/Impact/server/lib/perl/Convert/ASN1/_decode.pm line 108

This information supplements that in KA297946

Legacy ID:KA388337

This error occurs when improperly formatted traps are received by the snmp adapter.

To allow these traps to be processed you can comment out the 'die' statements from the <MCELL_HOME>\lib\perl\Convert\ASN1\_decode.pm file.

The line numbers may vary, but below are the exact lines that needs to be commented (the 2 commented lines)

=====================================>>>

redo CHOICELOOP if $seqof && $pos < $end;
next OP;
}
}
}
# die "decode error" unless $op->[cOPT];
}
}
}
}
# die "decode error $pos $end" unless $pos == $end;
}

sub _dec_boolean {

=====================================>>>

Once you have commented these lines please restart the adapter and confirm if you are now able to receive the snmp traps.

Please note that this is just a workaround and we recommend that you check why incorrect traps are being sent.
