# Packetbeat is missing long running transactions
Packetbeat has an internal timeout that it uses to time out transactions and TCP connections when no packets have been seen for a long time.
To process long running transactions, you can specify a larger value for the [`transaction_timeout`](/elastic/beats/pull/48499/reference/packetbeat/common-protocol-options#transaction-timeout-option) option. However, keep in mind that very large timeout values can increase memory usage if messages are lost or transaction response messages are not sent.
