What were you trying to do that didn't work?
In a GUI environment with multiple logged-in users, when a new user logs in or mount points change, the CPU usage of gvfsd-trash process for every logged-in user session increases simultaneously. This causes a spike in CPU usage that slows down the entire system.
What is the impact of this issue to you?
In a system which has hundreds of users and the users' home directories are in a NFS area mounted by autofs, the frequently login/logout or mount points changes will cause the whole system slows down.
Please provide the package NVR for which the bug is seen:
gvfs-1.36.2-18.el8_10.x86_64
How reproducible is this bug?:
Always.
Steps to reproduce
- Fresh install 2 RHEL 8.10 systems A and B. Setup A as an NFS client and VNC server. Setup B as an NFS server.
- Creates 5 user accounts(user001-user005) as vnc users and 500 user accounts(U0001-U0500) for testing the autofs mount.
- Setup the share directories.
## system B # for i in {001..005}; do mkdir -p /exports/home/user$i ; done # for i in {001..005}; do chown user$i:user$i /exports/home/user$i; done # for i in {001..005}; do cp -r /home/user$i/* /exports/home/user$i; done # for i in {0001..0500}; do mkdir -p /exports/home/U$i ; done # for i in {0001..0500}; do chown U$i:U$i /exports/home/U$i; done # cat /etc/exports /exports/home A_IP(rw,sync,no_root_squash,no_subtree_check) systemctl enable nfs-server systemctl start nfs-server exportfs -r ## system A # cat /etc/auto.master | grep -v ^# /misc /etc/auto.misc /net -hosts +dir:/etc/auto.master.d +auto.master /home /etc/auto.home --timeout=300 # cat /etc/auto.home * fstype=nfs4,rw,soft,intr,rsize=8192,wsize=8192 B_IP:/exports/home/&
4. From a VNC client, login to the GUI of system A with user002-005 and make sure the Trash is opened on each session.
# ps -aux | grep trash user002 5210 0.0 0.2 600424 4924 ? Sl 12:13 0:03 /usr/libexec/gvfsd-trash --spawner :1.18 /org/gtk/gvfs/exec_spaw/0 user003 26722 0.0 0.1 600404 3068 ?

5. On system A, test the CPU usage when the mount points frequently changes.

Expected results
The whole system won't slow down. The CPU usage of gvfsd-trash won't increase significantly.
Actual results
The system slowes down when a new user logins to the GUI or mount points change.
