Hi,

You've caught me trying to provoke mpatrol into complaining. Alas
changing this to 27 does not make a difference. The backtrace calls says:

#10 0x281be8dc in __mp_findsource () from /usr/local/lib/libmpatrol.so
#11 0x2835f99d in tzsetwall () from /lib/libc.so.5
#12 0x2835fd41 in localtime_r () from /lib/libc.so.5
#13 0x283602a5 in ctime_r () from /lib/libc.so.5

"request.cpp", lineno=248) at tlogger.cpp:65
#15 0x0804f1cb in main () at request.cpp:248

Tracing through the code for libc the tzsetwall is trying to manipulate
the environment.
