Good morning, we've recently had some strange message in /var/log/syslog. System: debian bullseye, kernel 5.10.0-21-amd64 and 5.10.0-22-amd64 gluster 10.3 The message look like: Apr 27 13:30:18 piggy kernel: [24287.715229] INFO: task glfs_fusenoti:2787 blocked for more than 120 seconds. Apr 27 13:30:18 piggy kernel: [24287.715327] Not tainted 5.10.0-22-amd64 #1 Debian 5.10.178-3 Apr 27 13:30:18 piggy kernel: [24287.715419] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

In the latest release i read something about fuse: https://docs.gluster.org/en/latest/release-notes/10.4/ "Fix fuse concurrency problems" but i checked the tickets and wasn't able to find something. However, i upgraded gluster client 10.3 -> 10.4, hoping that this fixes the hang-issue. Has anyone seen these messages before?
