syslog messages from tldcd

[KPS]

Hi,
We have a Storagetech Library L-700 connected via SAN through a switch to an HP rp5470. We're getting a message in the syslog about every 7 minutes saying the following:
Sep 22 14:07:01 bkupm3 tldcd[16652]: tldcd.c.2309, newfd = INVALID_SOCKET, newfd
=-1, timersig=1, error=4, EINTR=4, selectret=-1
Would anyone have any experience to know whether this is something we need to address on the server or if it's a connectivity issue with the switch or Tape Library Bridge??
Thanks,
-Ken
