On the SUN APP Server :-

$ ulimit -a

time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         2097148
stack(kbytes)        2097148
coredump(blocks)     unlimited
nofiles(descriptors) 1024
vmemory(kbytes)      unlimited

$ ulimit -Hs
2097148

NOTE - On a Digital Inix (5.1) APP Server , The Same Transaction/User Volume Runs Successfully Without Error whole ulimit is under :-

time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         419430
stack(kbytes)        2097152
memory(kbytes)       7416080
coredump(blocks)     unlimited
nofiles(descriptors) 4096
vmemory(kbytes)      2097152
