Hi

I have a customer that is getting the following line in the log, which brings the server to a standstill and stops work altogether.

2018-05-21 14:47:54 /THREAD(2) unexpected error from select(), retval=-1, errno=0 (Unknown error)

It eventually clears and everything seems fine. This only started yesterday and nothing has changes in their system.

thanks
Tayla

Kind Regards,
Tayla Anniciello
