[squid-users] squid 3.5.4 dies

[Dmitry Melekhov]

Hello!

Several days ago I updated my self-compiled squid 3.4 to 3.5.4,
server is ubuntu 12.04 x86-64.
All I see in logs is
2015/05/08 09:13:47 kid1| local=192.168.42.130:32785 
remote=74.125.205.132:443 FD 808 flags=1: read/write failure: (32)

I had 3.5.4 on test server , which is hardware and OS identical, but , 
definitely, has lower load,
it worked with 3.5 since it was released and no such problem.
Could you tell me how can I find where problem  is?

Thank you!
