shrihari commented on AMQ-8471:
-------------------------------
Below is the configuration of the linux machine:
cat /etc/os-release
NAME="SLES"
VERSION="12-SP2"
VERSION_ID="12.2"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP2"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles:12:sp2"
AMQ 5.16.2 (AMQ-8425)
local RET="`ps -eo "pid,args" | grep "^\s*$activemq_pid\s.*java"`"
This fix is working fine on linux
This fix doesn't work on AIX
Its better if you can somehow get the AIX machine as the issue happens all the
time when you invoke activemq stop.
> activemq stop command fails with no or outdated process id

> In some AIX/Linux environments, the activemq stop command fails with the
> below error.
> bash-4.4# ./activemq stop
> INFO: Loading '/AMQ/message-broker/bin/env'
> INFO: Using java '/usr/java8_64/bin/java'
> ERROR: No or outdated process id in '/AMQ/message-broker//data/activemq.pid'
> INFO: Removing /AMQ/message-broker//data/activemq.pid
>
> The fix provided in https://issues.apache.org/jira/browse/AMQ-8425 doesn't
> work in such environments as the issue is not due to the user/terminal
> instance.
>
> Workaround:
> Some AIX/linux environments are highly sensitive to the *acute/backquot*
> *character `*
> Backquot character reference :
> [https://www.computerhope.com/jargon/b/backquot.htm]
> Update the file <AMQ_HOME>/message-broker/bin/activemq as below :
> Change the line by removing backquot character :
> RET="`ps -eo "pid,args" | grep "\s*$activemq_pid\s.java"`" to RET="ps -eo
> "pid,args" | grep "\s$activemq_pid\s.*java""
> This will be inside checkRunning() function.
