<div class=Section1>
<p class=MsoNormal>I have been having a few issues recently. I’m running
Nut 2.4.3 on Solaris 10 (10/09) using a TrippLite SMART700DVa UPS. Everything
seems to be working fine except for some random issues. During a power cycle
(UPS online to offline to online) NUT will occasionally get disconnected from
the UPS. A call to it using upsc results in “Error: Data stale”. And
running dmesg has the following messages:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> UPS
ups@localhost on line power <o:p></o:p></p>
<p class=MsoNormal> UPS
ups@localhost on battery<o:p></o:p></p>
<p class=MsoNormal> Data
for UPS [ups] is stale – check driver<o:p></o:p></p>
<p class=MsoNormal> Poll
UPS [ups@localhost] failed – Data stale<o:p></o:p></p>
<p class=MsoNormal> Last
message repeated 2 times<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This will only happen once in every 50 times or so. I am not
sure where to look for the problem. Could it be a problem in NUT? Or Solaris or
the libusb? Or could it be a problem with the UPS? It has occurred on different
machines with different UPS’s, so I don’t think it is a hardware
issue. Has anyone else seen a problem like this? Or could point me in the right
direction to get this problem resolved? <o:p></o:p></p>
