| Summary | 0004828: 100% CPU eaten | ||||
| Description | The backend repeatedly asks /keys to exchange, even if it gets them right. That causes a ~ 100% CPU usage. | ||||
| Additional Information | That has only be noticed on my personal laptop. | ||||
| Tags | No tags attached. | ||||
| That's due to some misconfiguration that makes the 'Expires:' HTTP response header from "/keys" being set to 'now'. | |
| The fault was on *exchange's* code: the routine that sscanf's the HTTP "Expire: " header didn't allocate the extra byte for the null-termination of parsed strings. So unexpected variables got overwritten by the null-terminator, with the result of breaking the next reload of /keys. | |
| Fixed in eab7bb7 (exchange codebase) | |
