Hi All, The above error message gets logged in my cache.log. I turned on the debug level 5 for debug section 5 and I got this: 1999/03/24 15:50:29| commSetSelect: FD 232 type 1 1999/03/24 15:50:29| commSetTimeout: FD 232 timeout 86400 1999/03/24 15:50:29| comm_write: FD 232: sz 264: hndl 30fb0: data afcbcb0. 1999/03/24 15:50:29| comm_write: fd_table[232].rwstate != NULL 1999/03/24 15:50:29| commSetSelect: FD 232 type 2 Do you have any ideas? (host OS: Solaris 7, squid-version: 2.1-PATCH2 + patches) The error message occurs usually in rush hours and whenever such messages are logged random requests are stalled for a couple of seconds. Thanks in advance. Bertold
