Symptoms
The process 'queueprocd - pr' takes up a large amount of system resources and appears to be stuck processing cphulkd_block_brute_force tasks:
[15:53:17 root ~]cPs# ps fauxx | grep queue
root 773 1.3 0.1 83060 10720 ? Ss Sep28 45:33 queueprocd - waiting up to 1s to process a task
root 9893 52.3 0.8 236520 52568 ? S 01:48 442:28 \_ queueprocd - process - block_brute_force
root 15788 0.0 0.0 112812 972 pts/0 S+ 15:53 0:00 | \_ grep --color=auto queue
The task queue, especially for cphulkd_block_brute_force tasks, also begins to increase:
[14:38:50 root ~]cPs# ll /var/cpanel/taskqueue/groups/cphulk_block_brute_force | wc -l 91243
Description
This issue is caused by the queueprocd hanging when processing block_brute_force tasks. This can cause high CPU, Inode, and Disk usage due to the process itself and the increasing number of queued task files in the task queue as a result of the stuck process.
We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-38814. Follow this article to receive an email notification when a solution is published in the product.
Workaround
Clear out the task queue or move it elsewhere:
mv -v /var/cpanel/taskqueue{,.$(date +%s)}
Afterward, kill off the task or restart queueprocd:
/scripts/restartsrv_queueprocd
