Re: Monitor time statistics wrong (ITS#1984)

[asparks@quris.com]

Seem to have a problem w/ this patch, but am working around it.  My
monitoring script tried to access:

/opt/ldap/bin/ldapsearch -h ns01 -s base -b
cn=Current,cn=Time,cn=Monitor 'objectClass=*' description

This caused the server to dump core (signal 9) with traceback:
#0  0xff0c9cf0 in __sigprocmask () from /usr/lib/libthread.so.1
#1  0xff0bf324 in _resetsig () from /usr/lib/libthread.so.1
#2  0xff0bea48 in _sigon () from /usr/lib/libthread.so.1
#3  0xff0c194c in _thrp_kill () from /usr/lib/libthread.so.1
#4  0xff1395d8 in abort () from /usr/lib/libc.so.1
#5  0x23e158 in __eprintf ()
#6  0xb11d0 in monitor_subsys_time_update ()
#7  0xde4fc in monitor_entry_update ()
