| Summary | 0010313: /keys keeps files open to secmods when setup is incompleted | ||||
| Description | reproduced by florian, original found in default trixie setup I had some wallet asking for /keys, the exchange was delete and re-setup. When the httpd server was started the numbers of open files started to increase $ ss | grep exchange | wc -l 411 to /run/taler-exchange/secmod-<any>/server.sock until 500 and then the logs have WARNING `accept' failed at secmod_common.c:432 with error: Too many open files And exchange services stop responding so is not possible to complete the setup with the `offline` tool. | ||||
| Tags | No tags attached. | ||||
| Some further info: The sockets aren't just opened automatically, but whenever the exchange gets /keys requests (that subsequently hang). We'd expect that even then, the exchange only opens *one* connection to each secmod helper. But what *actually* happens is that the exchange opens a new connection to the secmod helpers on every (hanging) /keys request. | |
| (Easily reproducible locally via an exchange-httpd process and secmod processes, with a fresh DB, a coin config but without any offline setup. Just curl "/keys" and check number of open sockets.) | |
