Native port of Redis for Windows. Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs. This repository contains unofficial port of Redis to Windows.
Describe the bug/issue
After the continuous operation of the service, there was no response for nearly 25 hours.
During this time,the service background save is not executed, the client cannot connect, and there is no record in the windows system log.
Then, for some reason, it recovered itself.
To Reproduce
[8888] 16 Jun 10:46:59.054 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
[8888] 16 Jun 10:46:59.056 # Redis version=5.0.10, bits=64, commit=1c047b68, modified=0, pid=8888, just started
[8888] 16 Jun 10:46:59.056 # Configuration loaded
[8888] 16 Jun 10:46:59.060 Running mode=standalone, port=9876.
[8888] 16 Jun 10:46:59.060 # Server initialized
[8888] 16 Jun 10:46:59.062 DB loaded from disk: 0.001 seconds
[8888] 16 Jun 10:46:59.063 * Ready to accept connections
The configuration file only modifies requirepass, bind, port, timeout, dir and logfile.
After running continuously for more than 2 months, check that the maximum client list id is 1435529.
