Doc Text:	.Proxy daemon logs now update immediately Previously, log messages from the proxy daemon were buffered by the glibc library, causing delays in log file updates. As a result, in the event of a crash, some log entries could be lost, making troubleshooting and debugging more difficult. With this fix, messages are now written directly to the log file, bypassing glibc buffering, ensuring that logs are immediately visible.	Story Points:	---

Description Anoop C S 2025-04-04 13:19:25 UTC

Logs from libcephfs proxy daemon are getting buffered by libc and only appear in corresponding systemd journal once it is full. Depending upon the number of proxy client connections made this might take very long time until we see anything in the logs.
