1. MEM_ARGS changed multiple time to run bsu.sh -> changed 1024 and 2048 than finally updated with 3072 but still taking long time. 
2. Verified using GUI mode ./bsu.sh and 
3. even cleared cache_dir directory under "/d2/applprod/CRP1/fs1/FMW_Home/utils/bsu/cache_dir" 
4. Still taking long time for running 
applprod@example:~/CRP1/fs1/FMW_Home/utils/bsu$ ./bsu.sh -install -patch_download_dir=/d2/applprod/CRP1/fs1/FMW_Home/utils/bsu/cache_dir -patchlist=FMJJ -prod_dir=/d2/applprod/CRP1/fs1/FMW_Home/wlserver_10.3
