Piping logs to a java process : creates multiple processes

[Milind Vaidya <kavadsa@xxxxxxxxx>]

I am writing messages to error_log file as well as sending to std out.

The setting looks like 

ErrorLog  "| /usr/bin/tee -a /var/log/httpd/error_log |  java -cp producer.jar stdin.producer.StdInProducer /CustomProducer/config.json >> /producer_init.log 2>&1"`

When httpd is started it spawns 2 processes and adds one every one hour, keeping all alive

Only other thing happening per hour is rotation of error_log file by logrotate with copytruncate option (which copies the file data and truncates original file keeping the file descriptor unchanged )

I also tested it with another program with setting as follows which runs fine, so what am I doing wrong here ?

ErrorLog  "| /usr/bin/tee -a /var/log/httpd/error_log | /usr/bin/logger -u /tmp/apache_log.socket"
