  34 <PRE>&gt;<i>in addition to this db lose bug:
  35 </I>&gt;<i>i'm using services 4.5.42 and i'm experiencing the same thing
  36 </I>&gt;<i>services suddenly crash and sometimes the db files &quot;shrink&quot;
  37 </I>&gt;<i>this is very irretating and we had to run a process of backing up
  38 </I>&gt;<i>them every now and then (we have a large nick &amp; chan db's)
  39 </I>
  40      Do you mean you weren't backing them up before?  That's hardly
  41 responsible administration.  As for the data loss problem, if Services is
  42 interrupted while writing data then the old data can be recovered from the
  43 backup file in the same directory.  Services 5.0 is more robust about
  44 saving data and will not overwrite the old data file until the new one has
  45 been successfully written (so you will never see any data loss because of
  46 Services crashes--of course this doesn't rule out disk errors, system
  47 break-ins, etc.).
  48
  49 &gt;<i>ps. i've found the &quot;hackers&quot; on my net loading many bots
  50 </I>&gt;<i>and sending &quot;nickserv help&quot; and &quot;chanserv help&quot; commands from them
  51 </I>&gt;<i>right before services crashed. please check it.
  52 </I>
  53      This is most likely due to a write buffer overflow (what ircds call
  54 &quot;max SendQ exceeded&quot;).  Unfortunately this is not an easy problem to solve,
  55 but I'll see if I can make Services 5.0 slightly more robust in this area.
