by Over the past few weeks, we have been having problems with our RedHat
4.0 box. Apparently, named is NOT removing packets from the recieve
queue on UDP port 53. When the problem is*reported, the ps list
contains a "request-route" process in zombie, and several ipop3d
processes running (due to a machine on the network running active copies
of Netscape mail). For some reason, named seems to spontaineously
refuse to listen. Restarting named clears UDP port 53, but named will
not resume proper operation; packets continue to pile up on UDP port
53. Only a full shutdown and reboot seems to solve the problem.
However, proper operation only lasts for between 3 and 5 days, at which
point the packets again pile up on the port. We used to get runtimes in
excess of months.
I have tried upgrading to kernel 2.0.30, assuming it was a kernel
problem. This did not have any appreciable effect. All I seem to be
able to do is reboot the machine on a regular basis, but this is NOT an
acceptable solution. Can anybody help? Has this happened to anybody
else?
Thank you.
