Hi,

We are seeing following errors occasionally in the logs 

2021-11-18-13:55:59.171+02:00I----- 0x38AD5425 webseald ERROR wiv socket WsTcpListener.cpp 494 0x7f79f669b700 -- DPWIV1061E Could not write to socket (-1)

with two other variants 
Could not write to socket (104)
Could not write to socket (406)

Question is - are these purely client connection issues, e.g end user just quitting/connection breaking, or should we dig deeper into these? If latter, what would be best troubleshooting tactic for these?  Is there some way to correlate these errors to, say, access log entries? 

There would be this parameter for stopping logging of these messages,  https://www.ibm.com/docs/en/sva/10.0.2?topic=http-webseal-server-log-errors  but before applying that we would want to understand that we are just not sweeping the problem under the rug.

Hi,

I'm also interested on how to find out the cause for these errors and i have ongoing pmr for this.

If you look on coding against a socket it feels like it should be possible to output more information that just an error.

Hi Mikael,  if you get some information via PMR which would be generally useful in case like this, would you be so kind and share that?
