## Symptoms

- * `CKP_mutex::lock_206` files generate rapidly and cause 100% use of inodes.
* The system does not forward traffic and is not able to run drop debug.
* The commands result in "`No space left on device`" even though disk space is available.
* `# df -i` shows 100% use of inodes.
* The procedure in [sk95487](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk95487) shows that under `/var/opt/CPshrd-RXX/tmp` files with the name `CKP_mutex::lock_206` are generated rapidly and not deleted.

  <br />

## Cause

The `dlpu` process causes the issue.   

`[Expert@vsx-fw-4:0]# lsof | grep CKP_mutex::lock`  

`dlpu 60787 admin 2288u REG 253,4 0 2293964 /var/opt/CPshrd-R80.40/CTX/CTX00001/tmp/CKP_mutex::lock_206_8817783884A12AEC49B6F39CCE5A1D3AF9B3E1BE`  

The process creates these files in order to have rapid access to information and files. However, the process does not release the locks and therefore they are not deleted.
