Process Management

The process management page is used to view and manage processes running on the system.

Process List

The page displays all running processes in a table format.

The list displays the following information:

• PID: Process ID
• Name: Process name
• Parent PID: PID of the parent process
• Threads: Number of threads
• User: User running the process
• Status: Process status
• CPU: CPU usage
• Memory: Memory usage
• Start Time: Process start time

Process Status

Status	Description
Running	Process is executing
Sleeping	Process is waiting for an event
Blocked	Process is blocked
Idle	Kernel thread is idle
Stopped	Process has stopped
Waiting	Process is in uninterruptible wait
Locked	Process is in a locked state
Zombie	Process has ended but not been reaped

Search and Filter

• Search: Search by PID or process name
• Status Filter: Filter processes by status (All Status, Running, Sleeping, Stopped, Idle, Zombie, Waiting, Locked)
• Refresh: Reload the process list to fetch the latest data

The table columns PID, Name, Parent PID, Threads, CPU, Memory and Start Time can be clicked to sort the list.

The list is paginated. The page size can be set to 50, 100, 200 or 500 entries per page (50 by default), and a quick jumper is available to navigate directly to a specific page.

Process Operations

Left-click (or right-click) on a process to open the operation menu:

• View Details: View detailed process information
• Terminate (SIGTERM): Send SIGTERM signal (graceful termination)
• Kill (SIGKILL): Send SIGKILL signal (force kill)
• Stop (SIGSTOP): Pause the process
• Continue (SIGCONT): Resume a paused process
• Interrupt (SIGINT): Send SIGINT signal (equivalent to Ctrl+C)
• Hang Up (SIGHUP): Send SIGHUP signal
• User Signal 1 (SIGUSR1): Send the SIGUSR1 user-defined signal
• User Signal 2 (SIGUSR2): Send the SIGUSR2 user-defined signal

You can also double-click a process to open its details directly.

Sending any signal (including Terminate and Kill) first pops up a confirmation dialog showing the signal name and the target PID. The signal is only sent after you confirm.

Process Details

The details dialog shows the following basic information:

Field	Description
PID	Process ID
Parent PID	PID of the parent process
Name	Process name
User	User running the process
Status	Process status
Threads	Number of threads
CPU	CPU usage
Memory (RSS)	Resident set size (physical memory in use)
Virtual Memory	Virtual memory size
Swap	Amount of memory swapped out
Disk Read	Total bytes read from disk
Disk Write	Total bytes written to disk
Start Time	Process start time
Executable Path	Path to the executable file
Working Directory	Current working directory
Command Line	Full command line used to start the process

Below the basic information, the following sections are available as collapsible panels (each is only shown when the process has corresponding data):

• Environment Variables: Environment variables of the process
• Open Files: Files currently opened by the process
• Network Connections: Network connections of the process, listed as local address:port -> remote address:port (status)

Common Processes

Process	Description
nginx	Nginx web server
php-fpm	PHP FastCGI process manager
mysqld	MySQL database service
postgres	PostgreSQL database service
dockerd	Docker daemon
ace	AcePanel panel process

Notes

1. Ending critical system processes may cause system instability
2. Ending the panel process will make the panel inaccessible
3. It is recommended to only end processes that are confirmed to be useless
