Important

The SingleStore 9.1 release candidate (RC) is available now. It will be promoted to general availability (GA) soon and at that time it will be renamed to SingleStore 10.

In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10, while SingleStore 9.0 is recommended for production workloads.

Deleting Trace Log

On this page

Tracelog files can be very useful to understand the root cause of specific issues and troubleshoot them, so SingleStore recommends to keep a copy of these files within or outside of your cluster. However, you may safely delete the tracelog files should disk space utilization become a concern. If you are deleting tracelog files, make sure to send a kill -SIGHUP to the memsqld process.

Example:

ps -ef|grep memsql
memsql 2462 1 0 Jan15 ? 00:00:01 /opt/singlestoredb-server-7.6.8-ad67e74046/memsqld_safe --defaults-file /opt/memsql/Lf1/memsql.cnf --user 1008 --auto-restart StagedEnable
memsql 2474 2462 19 Jan15 ? 8-08:46:41 /opt/singlestoredb-server-7.6.8-ad67e74046/memsqld --defaults-file /opt/memsql/Lf1/memsql.cnf --user 1008
memsql 2624 2474 0 Jan15 ? 00:00:00 /opt/singlestoredb-server-7.6.8-ad67e74046/memsqld --defaults-file /opt/memsql/Lf1 memsql.cnf --user 1008
kill -SIGHUP 2474
kill -SIGHUP 2624
