Airwave error - ttyS0: tcgetattr: Input/output error

    Posted Feb 09, 2018 10:46 AM

    Every few seconds this error shows up in our airwave syslog:

     

    ttyS0: tcgetattr: Input/output error

     

    We're on v 8.2.5.1. Any help would be greatly appreciated.

     

    Thank you!

    In 8.2.5, serial port was enabled by default.  Is your AMP running on a VM or hardware that doesn't have a serial port?  If so, then these errors can be ignored.

    Thanks for the reply. Correct, it's on a vm without a serial port. Is there a way to prevent these errors from sending out syslog messages, rather than having to set up a filter to ignore them on our syslog server?

    Thanks,

    Mike

    You'll have to open a support case.  Support can open the support shell and perform the changes to disable.  Also, you can mention the defect DE30738 to get it up-prioritized so you don't have to redo this change in the future.
