When Cells has been running a while this message appears in the logs, then repeats every 30s ```auto Sep 27 18:51:20 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:51:20+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:51:21 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:51:21+01:00","logger":"pydio.web.auth","msg":"keys rotated, next rotation: 2019-09-27 23:51:21.284836259 +0000 UTC"} Sep 27 18:51:51 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:51:51+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:51:51 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:51:51+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} Sep 27 18:52:21 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:52:21+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:52:21 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:52:21+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} Sep 27 18:52:51 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:52:51+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:52:51 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:52:51+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} Sep 27 18:53:21 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:53:21+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:53:22 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:53:22+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} Sep 27 18:53:52 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:53:52+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:53:52 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:53:52+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} Sep 27 18:54:22 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:54:22+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:54:22 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:54:22+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} Sep 27 18:54:52 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:54:52+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 18:54:53 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T18:54:53+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: keys already rotated by another server instance"} ``` and so on. This doesn’t seem to cause a problem using Cells, but it seems odd, and there are other issues where I have to restart Cells every so often. ([Websocket 502 error](https://forum.pydio.com/t/websocket-502-error/2787/5)) Prior to the above messages is: ```auto Sep 27 12:45:37 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:45:37+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 12:46:29 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:46:29+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: update: Error 1205: Lock wait timeout exceeded; try restarting transaction"} Sep 27 12:46:59 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:46:59+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 12:47:52 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:47:52+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: update: Error 1205: Lock wait timeout exceeded; try restarting transaction"} Sep 27 12:48:22 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:48:22+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 12:49:13 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:49:13+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: update: Error 1205: Lock wait timeout exceeded; try restarting transaction"} Sep 27 12:49:43 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:49:43+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 12:50:34 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:50:34+01:00","logger":"pydio.web.auth","msg":"failed to rotate keys: update: Error 1205: Lock wait timeout exceeded; try restarting transaction"} Sep 27 12:51:04 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:51:04+01:00","logger":"pydio.web.auth","msg":"keys expired, rotating"} Sep 27 12:51:50 cust-upload cells[995225]: {"level":"info","ts":"2019-09-27T12:51:50+01:00","logger":"pydio.web.auth","msg":"keys rotated, next rotation: 2019-09-27 17:51:04.210933878 +0000 UTC"} ``` ---
