Our adsm server was working fine utill before yesterday and it is
runningon sp2/aix 4.1 machine. From tuesday, It give me error - no
enough space in recovery log. I added some space on tuesday.

Today, it still give me message:
"The server does not have enough recovery log".

question:
1. Why %Util are reduce from 77.2 reduce to 0.3 after reboot?
2. It seems after the first node backup finished the recorvery log will
   be full and then other node can not backup any more - what problem it
   is?
3. How can I fix it? ( I don't think the add more log space is useful )

Any comments will be appreciated

Thanks in advance
