I can see that client sends SEQUENCE every 60 sec. And this is for some hours ( ~8 ). At some point client sends SEQUENCE after 127 seconds and gets, as expected, EXPIRED. I this point I have to blame myself. Client comes with EXCHANGE_ID using the same clientid. We did not garbage collected clientid internally as this happens after 2*LEASE_TIME and return EXPIRE. This ping-pong never ends. This is probably mostly a bug on my side. Nevertheless we never observed late SEQUENCE with kernel > 2.6.39. A short packet dump attached. I can open bug at RHEL if required. Regards, Tigran. --f46d043be05e5feaa704b496bfcc Content-Type: application/octet-stream; name="sequence.dump" Content-Disposition: attachment; filename="sequence.dump" Content-Transfer-Encoding: base64 X-Attachment-Id: f_gwg3pfq90 1MOyoQIABAAAAAAAAAAAAP//AAABAAAAv83wTogRAwDWAAAA1gAAAAAADJ/wRwAjrv3txAgARQAA yMs1QABABtA9g6lHO4OpUC8D8QgBcW/7/ER/PjyAGAH1n3cAAAEBCAoWo7GWIJVVkYAAAJBoRhMC AAAAAAAAAAIAAYajAAAABAAAAAEAAAABAAAAOABHVOkAAAAIcDMtd2dzMTMAAAAAAAAAAAAAAAcA AAAAAAAAAQAAAAIAAAADAAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1TuteiAAA AAYAAAAAAAAABAAAAg0AAAAAAAAAAAAAAAC/zfBOKR0DAJYAAACWAAAAACOu/e3EABtUwmDBCABF AACICr1AAD8GkfaDqVAvg6lHOwgBA/FEfz48cW/8kIAYDAn60QAAAQEICiCWP/EWo7GWgAAAUGhG EwIAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAADUAAAAATuteiAAAAAYAAAAAAAAA BAAAAg0AAAAAAAAAAAAAAAAAAAAA+83wToQRAwDWAAAA1gAAAAAADJ/wRwAjrv3txAgARQAAyMs3 QABABtA7g6lHO4OpUC8D8QgBcW/8kER/PpCAGAH1n3cAAAEBCAoWpJv2IJY/8YAAAJBpRhMCAAAA AAAAAAIAAYajAAAABAAAAAEAAAABAAAAOABHVSUAAAAIcDMtd2dzMTMAAAAAAAAAAAAAAAcAAAAA AAAAAQAAAAIAAAADAAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1TuteiAAAAAYA AAAAAAAABAAAAg4AAAAAAAAAAAAAAAD7zfBOXhMDAJYAAACWAAAAACOu/e3EABtUwmDBCABFAACI Cr5AAD8GkfWDqVAvg6lHOwgBA/FEfz6QcW/9JIAYDAkkKwAAAQEICiCXKk0WpJv2gAAAUGlGEwIA AAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAADUAAAAATuteiAAAAAYAAAAAAAAABAAA Ag4AAAAAAAAAAAAAAAAAAAAAN87wToMRAwDWAAAA1gAAAAAADJ/wRwAjrv3txAgARQAAyMs5QABA BtA5g6lHO4OpUC8D8QgBcW/9JER/PuSAGAH1n3cAAAEBCAoWpYZWIJcqTYAAAJBqRhMCAAAAAAAA AAIAAYajAAAABAAAAAEAAAABAAAAOABHVWEAAAAIcDMtd2dzMTMAAAAAAAAAAAAAAAcAAAAAAAAA AQAAAAIAAAADAAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1TuteiAAAAAYAAAAA AAAABAAAAg8AAAAAAAAAAAAAAAA3zvBOXRMDAJYAAACWAAAAACOu/e3EABtUwmDBCABFAACICr9A AD8GkfSDqVAvg6lHOwgBA/FEfz7kcW/9uIAYDAlNggAAAQEICiCYFKsWpYZWgAAAUGpGEwIAAAAB AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAADUAAAAATuteiAAAAAYAAAAAAAAABAAAAg8A AAAAAAAAAAAAAAAAAAAAc87wToMRAwDWAAAA1gAAAAAADJ/wRwAjrv3txAgARQAAyMs7QABABtA3 g6lHO4OpUC8D8QgBcW/9uER/PziAGAH1n3cAAAEBCAoWpnC2IJgUq4AAAJBrRhMCAAAAAAAAAAIA AYajAAAABAAAAAEAAAABAAAAOABHVZ0AAAAIcDMtd2dzMTMAAAAAAAAAAAAAAAcAAAAAAAAAAQAA AAIAAAADAAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1TuteiAAAAAYAAAAAAAAA BAAAAhAAAAAAAAAAAAAAAABzzvBOJBoDAJYAAACWAAAAACOu/e3EABtUwmDBCABFAACICsBAAD8G kfODqVAvg6lHOwgBA/FEfz84cW/+TIAYDAl21wAAAQEICiCY/wsWpnC2gAAAUGtGEwIAAAABAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAADUAAAAATuteiAAAAAYAAAAAAAAABAAAAhAAAAAA AAAAAAAAAAAAAAAAuc7wTmKDAQDWAAAA1gAAAAAADJ/wRwAjrv3txAgARQAAyMs9QABABtA1g6lH O4OpUC8D8QgBcW/+TER/P4yAGAH1n3cAAAEBCAoWp4HAIJj/C4AAAJBsRhMCAAAAAAAAAAIAAYaj AAAABAAAAAEAAAABAAAAOABHVeMAAAAIcDMtd2dzMTMAAAAAAAAAAAAAAAcAAAAAAAAAAQAAAAIA AAADAAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1TuteiAAAAAYAAAAAAAAABAAA AhEAAAAAAAAAAAAAAAC5zvBOTYUBAJYAAACWAAAAACOu/e3EABtUwmDBCABFAACICsFAAD8GkfKD qVAvg6lHOwgBA/FEfz+McW/+4IAYDAlS4wAAAQEICiCaEAoWp4HAgAAAUGxGEwIAAAABAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAADUAAAAATuteiAAAAAYAAAAAAAAABAAAAhEAAAAAAAAA AAAAAAAAAAAAOM/wTvoZAgDWAAAA1gAAAAAADJ/wRwAjrv3txAgARQAAyMs/QABABtAzg6lHO4Op UC8D8QgBcW/+4ER/P+CAGAH1n3cAAAEBCAoWqXH+IJoQCoAAAJBtRhMCAAAAAAAAAAIAAYajAAAA BAAAAAEAAAABAAAAOABHVmIAAAAIcDMtd2dzMTMAAAAAAAAAAAAAAAcAAAAAAAAAAQAAAAIAAAAD AAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1TuteiAAAAAYAAAAAAAAABAAAAhIA AAAAAAAAAAAAAAA4z/BOoBsCAHIAAAByAAAAACOu/e3EABtUwmDBCABFAABkCsJAAD8GkhWDqVAv g6lHOwgBA/FEfz/gcW//dIAYDAnYLQAAAQEICiCb+jYWqXH+gAAALG1GEwIAAAABAAAAAAAAAAAA AAAAAAAAAAAAJxsAAAAAAAAAAQAAADUAACcbOM/wTo8dAgDWAAAA1gAAAAAADJ/wRwAjrv3txAgA RQAAyMtBQABABtAxg6lHO4OpUC8D8QgBcW//dER/QBCAGAH1n3cAAAEBCAoWqXH/IJv6NoAAAJBu RhMCAAAAAAAAAAIAAYajAAAABAAAAAEAAAABAAAAOABHVmIAAAAIcDMtd2dzMTMAAAAAAAAAAAAA AAcAAAAAAAAAAQAAAAIAAAADAAAABAAAAAYAAAAKAAAAAAAAAAAAAAAAAAAAAQAAAAEAAAA1Tute iAAAAAYAAAAAAAAABAAAAhMAAAAAAAAAAAAAAAA4z/BOtB4CAHIAAAByAAAAACOu/e3EABtUwmDB CABFAABkCsNAAD8GkhSDqVAvg6lHOwgBA/FEf0AQcXAACIAYDAnWZwAAAQEICiCb+jcWqXH/gAAA LG5GEwIAAAABAAAAAAAAAAAAAAAAAAAAAAAAJxsAAAAAAAAAAQAAADUAACcbOM/wTg4fAgDyAAAA 8gAAAAAADJ/wRwAjrv3txAgARQAA5MtCQABABtAUg6lHO4OpUC8D8QgBcXAACER/QECAGAH1n5MA AAEBCAoWqXIAIJv6N4AAAKxvRhMCAAAAAAAAAAIAAYajAAAABAAAAAEAAAABAAAAOABHVmIAAAAI cDMtd2dzMTMAAAAAAAAAAAAAAAcAAAAAAAAAAQAAAAIAAAADAAAABAAAAAYAAAAKAAAAAAAAAAAA AAAAAAAAAQAAAAEAAAAqTu+J6RFzScUAAAAhMTMxLjE2OS43MS41OS9wMy13Z3MxMy5kZXN5LmFm cy8xAAAAAAAAAQAAAAAAAAAAOM/wTj8gAgByAAAAcgAAAAAjrv3txAAbVMJgwQgARQAAZArEQAA/ BpITg6lQL4OpRzsIAQPxRH9AQHFwALiAGAwJ1JEAAAEBCAogm/o3FqlyAIAAACxvRhMCAAAAAQAA AAAAAAAAAAAAAAAAAAAAACcbAAAAAAAAAAEAAAAqAAAnGw== --f46d043be05e5feaa704b496bfcc--
