Many logs: Connection error: ssl_passthru:3778: not SSL (40)

Hi,

 

tmm3[10956]: 01260009:4: Connection error: ssl_passthru:3778: not SSL (40)

 

I'm receiving many this warnings in LTM log. I seen this before in my LTM log in version 11.4, but now (after upgrade to 12.1.1) this message is also send to my remote syslog. I can ignore this message and make filter in my remote syslog but I'm worried that I miss out some message. So, how to diagnose this problem? How can I found the VS that generate this message and resolve this problem. Now we have so many messages in log that we can't focus or see other problems/messages.

 

Thank You

    I'm concerned about the same now that we are beginning to test with 12.1.1.. We have noticed small 'floods' of logs such as: Connection error: ssl_null_parse:3109: record length too large (22)

     

    and this is just a small test session... scale that to full production and we may be in trouble. any word on how to deal with this???... oh, just realized you posted this today...
