The time period between getting pid of haproxy service and checking existance of pid file is very short, if with in this period haproxy service get reload then the race condition occured and container get exit as extend_start.sh script exit. To minimize the risk of race condition, this patch let the extend_start.sh script to try upto 3 times before exit. Closes-Bug: #1479888 Change-Id: I2f9b7ec832dec8d94a2cdd27ca8a212d0c65a60d
