0509-136 Errors with nmon TL8

I am attempting to use nmon (latest version from wiki) on an AIX TL8 system. When I start nmon (under root), I receive the following errors:

exec(): 0509-036 Cannot load program ./nmon because of the following errors:
0509-130 Symbol resolution failed for nmon because:
0509-136 Symbol lpar_get_info (number 15) is not exported from
dependent module /usr/lib/libc.a(shr.o).
0509-136 Symbol localtime64 (number 52) is not exported from
dependent module /usr/lib/libc.a(shr.o).
0509-136 Symbol perfstat_partition_total (number 90) is not exported from
dependent module /lib/libperfstat.a(shr.o).
0509-192 Examine .loader section symbols with the
'dump -Tv' command.

Any ideas what could be going on here? Thanks for any help.

Nigel Griffiths has a forum at IBM up, best discuss it right with him or search their forum 1st before posting there.

We are running TL8 SP2 and the latest nmon with no problems.

try with one version earlier , like 10
you got this error running nmon in foreground , try running in batch mode with nmon -x for example

hope this helps
bye
