| Summary | 0004482: merchant sometimes crashes with SIGSEVG | ||||
| Description | The full coredumps are on test-blue@tripwire. From the stack trace I assume it has to do with the key fetching logic ... | ||||

| might not be related, but if the config contains a non-existent exchange and CTRL-C gets pressed after the first failing attempt to get /keys, then the merchant segfaults. | |
| You reported this against the merchant, but the stack trace is for the exchange: taler-exchange-httpd_keystate.c:1002 Something is fishy here... | |
| Added assertions to help debug this in 025fbdb..eabbafc | |
| Oops, I posted the wrong stack trace. But still, there are also merchant stack traces in there: test-blue@tripwire:~$ ls *core* core.libmicrohttpd.23610.tripwire.1461759725 core.taler-merchant-.23613.tripwire.1461759760 core.taler-merchant-.15342.tripwire.1462263261 core.taler-merchant-.3716.tripwire.1462207199 | |
| Is this issue still current? | |
| That was impossible to reproduce, and might also have "accidentally" fixed. So I suggest to close, and if the problem is still there, it will come back. Ok? | |
