Description

On Solaris platform, the restriction of ps command does not allow the Karaf Service Wrapper to properly manage associated karaf process:

[root ~] # cat /opt/smartcollector-dev2/smartcollector-dist-5.7.5-SNAPSHOT/smartcollector-dev2.wrapper.pid
6043
[root ~] # ps -p 6043 -o comm
COMMAND
/opt/smartcollector-dev2/smartcollector-dist-5.7.5-SNAPSHOT/bin/smartcollector-

As we can see, if the path to wrapper executable is too long, il will cause the service to fail to stop associated karaf instance, as detailed below:

[root ~] # /etc/init.d/smartcollector-dev2 status
Removed stale pid file: /opt/smartcollector-dev2/smartcollector-dist-5.7.5-SNAPSHOT/smartcollector-dev2.wrapper.pid
smartcollector-dev2 is not running.

[root ~] # ps -ef | grep smartco
smcdev  6043     1   0 02:20:27 ?           0:01 /opt/smartcollector-dev2/smartcollector-dist-5.7.5-SNAPSHOT/bin/smartcollector-
smcdev  6044  6043   0 02:20:28 ?           4:11 /opt/smartcollector-dev2/smartcollector-java/bin/java -Djava.endorsed.dirs=/opt

[root ~] # /etc/init.d/smartcollector-dev2 stop
Stopping smartcollector-dev2...
smartcollector-dev2 was not running.

[root ~] # ps -ef | grep smartco
smcdev  6043     1   0 02:20:27 ?           0:01 /opt/smartcollector-dev2/smartcollector-dist-5.7.5-SNAPSHOT/bin/smartcollector-
smcdev  6044  6043   0 02:20:28 ?           4:11 /opt/smartcollector-dev2/smartcollector-java/bin/java -Djava.endorsed.dirs=/opt

This issue can also appears on HP-UX platform, where default ps command is also limited to a certain amount of characters (it seems to be 128).
