[hunchentoot-devel] Socket errors during requests

[Andrei Stebakov]

My log is full of messages like:
[2009-05-05 19:29:29 [ERROR]] Error while processing connection: I/O timeout
reading #<SB-SYS:FD-STREAM for "a socket" {D0CDBA9}>

If I trap the error stack it's like this:

0: (SB-DEBUG::MAP-BACKTRACE #<CLOSURE (LAMBDA #) {CFFA47D}>)[:EXTERNAL]
1: (BACKTRACE 536870911 #<SB-IMPL::STRING-OUTPUT-STREAM {CFB5DA1}>)

       :STATE 1)
    #<SB-THREAD:THREAD "Hunchentoot worker (client: 127.0.0.1:44453)"

What could be the reason for the errors?

Thank you,
Andrei
