DB::Exception: ODBCBridgeHelper: clickhouse-odbc-bridge is not responding #4456
Comments
This means that some hosts are OK and some have clickhouse-odbc-bridge is not responding? You can set logging files for
|
Yes, most of hosts works correctly. Also there is propagated error in clickhouse.server.err.log Its happened not always, sometime there is only 1-10 loops and then exception reported.
EDIT: Probably second exception "Received signal Aborted (6)" not related to first one |
cat /var/log/clickhouse-server/clickhouse-odbc-bridge.log
error log is empty Looks like problem at clickhouse side. Or, maybe, ipv6 bound server? |
|
Looks like abort is unrelated to this issue, server do not crash on this error and correctly return it to client ODBC bridge is also available
Looks like that |
Finally, solved by downgrading to 19.1.6 Unfortunately, can't figure out exact version with regression yet |
This is impossible, server always shutdown after abort signal. |
I think abort caused by another error, not related to clickhouse-odbc-bridge is not responding because it heppend 6 days later (see timestumps)
ODBCBridgeHelper: clickhouse-odbc-bridge is not responding do not crash server, just return error message to HTTP client Example of such error from client side:
Number of lines varies from one to thousands. |
On 19.4.2 revision 54416, with same simptoms, helped command |
On version 19.7.3.9 (official build) with same symptoms |
The error occurs when you restart the ClickHouse server or restart the server itself. |
@alesapin Do I remember correctly that we have observed similar issue recently? |
Yes, probably it's a problem with a too-small timeout. It's fixed in #10990. Also we had a lot of fixes in the dictionaries loader. |
I think this issue can be closed. |
I also encountered the same problem in the newer version, the specific link is https://github.com/ClickHouse/ClickHouse/issues/21322 |
