The SDK version we are using is 3.0.0 and the OS is HP-UX. Following are the contents of the .profile where we have turned on Centera SDK logging

But the file centeradebug.log is not appending, most of the times the size of the file decreases.

# uncomment the next 2 lines to switch on sdk logging
FPLIBRARY_LOG_FILE_DEBUG=/var/opt/stage/disco/logs/centeradebug.log
export FPLIBRARY_LOG_FILE_DEBUG
set FP_LOGPATH=/var/opt/stage/disco/logs/centeradebug.log
export FP_LOGPATH
set FP_LOGLEVEL=4
export FP_LOGLEVEL
set FP_LOGKEEP=APPEND
export FP_LOGKEEP
