Andy Kurth resolved VCL-817.
----------------------------
Resolution: Fixed
> pgrep command arguments have changed with RHEL/CentOS 7.x
> ---------------------------------------------------------

> Key: VCL-817
> URL: https://issues.apache.org/jira/browse/VCL-817
> Project: VCL
> Issue Type: Improvement
> Components: vcld (backend)
> Reporter: Andy Kurth
> Assignee: Andy Kurth
> Fix For: 2.4
>
>
> We use {{pgrep -fl}} in a few places. This used to return the full command
> names for each matching process. This no longer seems to be the case with
> 7.x. The command names are truncated. There is a new {{-a}} switch which
> causes the full names to be displayed. Unfortunately, the {{-a}} switch is
> not available on earlier versions and the command fails if it is included.
> Code needs to be updated to detect which switches are available and then
> assemble the correct command.
> This is very important. pgrep is used to ensure multiple processes aren't
> forked for the same reservation.
