Strange uptimes on smpp connections..

Hi there,
 
I know this has been reported in the past, but Ive noticed it again... We
have around 12 smpp connections out from our kannel server, and most of the
uptimes are what i would expect, however some are off, ie:
 
<smsc>
  <name>SMPP:smpp1.xxx</name>
  <id>smpp1</id>
  <status>online 38909s</status>
  <received>118</received>
  <sent>147</sent>
  <failed>2</failed>
  <queued>0</queued>
 </smsc>
<smsc>
  <name>SMPP:smpp2.xxx</name>
  <id>smpp2</id>
  <status>online 1075901068s</status>
  <received>12</received>
  <sent>8</sent>
  <failed>0</failed>
  <queued>0</queued>
 </smsc> 
 
 
This is from version cvs-20040202, and both were started at the same time
and havent dropped as far as i know.
 
Let me know what kind of info to look at to try and trace it - Im not sure
where to find it!
 
Cheers,
Bill.
