</div>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have 4 FI800s that are exhibiting what I would call a
memory leak. The setup has not changed much in years, but the issue
appears to have been happening for a month or so. The memory usage will
increase daily by about 2% until it maxes out, eventually requiring a
reboot. There is nothing very special about the config, multiple vlans
with virtual interfaces. Four switches total are deployed, 2 are
utilizing static routing. One is running higher CPU utilization, but
appears to be normal and appropriate for number of L3 interfaces. Code
version 07.6.02dT53. No errors, nothing particular in the log.
Traffic on the boxes is not particularly heavy, there are maybe a dozen or so
interfaces running less than 1%, the key Gige uplinks are at about 6%. To
me it appears to be "bad traffic" not too much traffic.<br>
<br>
Under IP statistics "other errors" is incrementing fairly quickly as
is "no port" number under UDP. Tomorrow I am going to attempt
to do some packet captures and maybe capture some of the traffic. Is
there any way to get more detail from the FastIron itself about the
errors? <br>
